  For some people, knocking three times means you want them. But if it’s twice on the pipe, the answer is no.
context: This is a friendly reminder to read our rules.
  Remember, /r/Showerthoughts is for showerthoughts, not "thoughts had in the shower!"
  (For an explanation of what a "showerthought" is, please read this page.)

  Did something fall on the floor? Maybe a bird flew into the window? Am I hearing things?
  It’s not considered weird. It’s confusing. >
  
  This. A single knock can't be discerned from an accidental noise. This is why we knock more than once. >
  
  *throws two rocks at someone's door >
  
  *makes two birds fly into someone's window* >
  
  Worst superpower ever >
  
  Pretty bad till exactly two birds “accidentally” fly into you >
  
  Also that'd be funny to do to your friend all the time. Three knocks and they check and see three birds, cries in anguish >
  
  You could be Birdman/Birdwoman for so many reasons >
  
  3  knocks are the correct minimum number, enough to establish a pattern, and direction, and get attention. >
  
  I consider 1 knock to be an accident, 2 knocks to be a courtesy for a door you're going to go through anyway but want to alert the occupants first, and 3 knocks to be an actual "request" for entry. >
  
  The two knocks is like what you get at the doc office when they come in. >
  
  or when you have a package delivery just notifying you it's there but you don't have to come to the door >
  
  I knock 0 times and stand at the door. People think it's weird too. >
  
  Knocks 0 times, rings doorbell instead >
  
  10 times >
  
  Honestly, count out 10 knocks in your head. It doesn't seem that weird. >
  
  If someone knocked at my door 10 times I wouldn't let them in. That's HELLA weird >
  
  I'm just gonna stand there and keep knocking. Not one time. Not two. Just gonna keep going. Not gonna stop till that door is open >
  
  Why stop when the doors open? Just keep it going even after it's been opened. >
  
  Just start punching the guest lightly as they open the door >
  
  You're knocking on your own door? >
  
  Yeah, wtf? u/Random_Loaf , could you provide context to why you would be knocking on your own door? >
  
  You don't? >
  
  I do not. Also, if your guest is just gonna open the door, why knock at all? >
  
  I have realized my typing error >
  
  I was just joking around. Sorry... >
  
  Oh no I was having a great time but I genuinely didn't realize I made a typing error lmao >
  
  “First shalt thou approach the door. Then, shalt thou knock three times. No more. No less. Three shalt be the number thou shalt knock, and the number of the knocking shall be three. Four shalt thou not knock, nor either knock thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then, the door shalt open… unless thou art naughty in my sight… and thou shalt be snuffed.” >
  
  I understood that reference >
  
  5 times. 7 times if I feel like finishing the jingle.
  Shave and a haircut....two bits. >
  
  I know exactly the pattern you’re describing. Must be universal 😂 >
  
  it's the "one  two-three-four  five"
  I use it as well >
  
  I believe you're right.
  If someone knocks once, don't answer the door, they're probably weird. >
  
  What if I knock continuously, until you open the door? >
  
  Then you’re weird too and getting the sprinklers. >
  
  Because someone might not notice once. Once might be something hitting the door instead of someone knocking. Twice shows a pattern at least. >
  
  knock knock knock Penny! knock knock knock Penny! Knock knock knock Penny! >
  
  knock knock knock JESSIE! knock knock knock JESSIE! >
  
  People don't knock anymore they text to say "hey, I'm outside" >
  
  That would be a scene in 'The Office' >
  
  Yeah it's a bit weird, cause no one would ever knock once in doors. Especially if they don't tell who they are and just knocking out. People usually do it for at least three times. >
  
  it's done more than once to let the person who hears it know that it was intentional
  a single knock is more likely to be an accidental bump >
  
  I usually go "Squidward! Squidward! Squidward! Squidward!" And when they open the door I start hitting their face >
  
  Not in the military. You’re instructed to knock once and only once. Then listen for a response whether to enter. Formal situations mostly. Obviously “house rules” don’t apply, like if you need to ask the boss something, still knock normally on the frame of an open door and wait for a response. >
  
  Came here to say this. It's been more than a quarter century, but I think the formal reporting procedure we learned was to knock once (on the frame, assuming the door is open), stand at attention, wait to be acknowledged, and then walk straight to the front of the desk, salute, and give your reporting statement.
  And yeah, one knock always felt super weird to me. >
  
  Do it as a streamlined Sheldon Copper
  Knock Penny

  Knock Penny >
  
  Twice is the minimum number to distinguish it from an unintentional or non important sound >
  
  Humans love patterns and knocking once isn't a pattern, it's just random. >
  
  Thats because everyone knows it’s “Knock knock, who’s there?” Not “ knock who’s there “ >
  
  My default knock is four times, rapidly.
  knockknockknockknock
  Yes, I enjoy Dr. Who, how could you tell? >
  
  I’ll never forget the four drum beats. >
  
  I knock the mario theme but don’t do the last note (da da da - da da - da ..) >
  
  I can't not knock the Terminator theme... It's also weird no one has every noticed.
  DUN-DUN-DUN.....DUn-DUn >

  Once: “I’m a friend who’s messing with you.”
  Twice: “I’m coming in as I knock.”
  3 times: “may I come in?”
  4 times (regularly): “hey it’s a close friend or significant other!”
  4 times (pounded): “police, open up!”
  5 times: “come open the door, I’m in a hurry.” >
  
  Once can be an accidental bump, more indicates intentional noise making >
  
  This is the real answer >
  
  In the military when you’re in trouble with your commander you have to knock exactly once. It’s awful. >
  
  My family has had a habit of hitting the wall of the house beside the driveway now I know if someone knocks on the door they are a stranger. >
  
  I just realized I need to start saying thrice more often in real life. >
  
  Lol, just depends on the person who is hearing the knock. Not the only doing the knocking
  Tbh knocking could be seen as a test for the knockee as to whether they have good hearing. But also being able to distinguish between a knock and other noices >
  
  I started doing this as a bit when I would knock on my sister's room's door. Now it's just my way of letting her know who it is that's knocking >
  
  My wife knocks once when she thinks I’ve been in the bathroom too long…. Really fucking hard. >
  
  Any old squirrel can knock once. We invented multiple knocks to keep the squirrels out. >
  
  A single knock could be caused by something bumping into your door. 2 or more knocks is a lot less likely to happen by chance, so it makes for a better signal >
  
  To me it seems like knocking is a form of expression like… Hi I’m here or Please come to the door. One knock would feel rude, like as if I were to say Now, or Here, or Open. >
  
  someone delivered a package at my house the other day and just knocked once loudly >
  
  Why knock at all? Just stand outside the door and text 'Here' like everyone else >
  
  One knock is closer to natural accident and brain tends to ignore those. 2/3/4 are harder to be a squirrel, a bat, or whatever you mioght spect it to be, says clearly enough 'Me who knoks am worthy of you stand your comfy arse and came open', me thinks. >
  
  This whole thing makes sense until you copied a "human" are you a robot lol >
  
  No... to the best of my knowledge, hundred per cent hooman. >
  
  Hmmm that sure sounds like something a robot would say Mr. JOE-9000 >
  
  I surrender, sheriff, hold your trojan... captcha?... tazer? >
  
  All of the above. >
  
  Knocking five times is psychotic. Like are zombies chasing you? >
  
  For some people, knocking three times means you want them. But if it’s twice on the pipe, the answer is no. >
  
  If you knocked once every 10 minutes for an hour, is it considered 1 or 6 knocks? >
  
  Then got people who rings the door bell a bunch of times gets annoying like some people don’t have the patience to wait 5 to 10 minutes of waiting happen to anyone before  . >
  
  One knock is how people I work with move between hotel rooms when on tour.  Nobody knocks once so it must be someone I know. >
  
  Vanilla Ice knocks only once, so I would also ignore this style of knocking >
  
  my personal knock is the pronounced drum beat from cake's "the distance" >
  
  Knock knock knock

  What if you knock once every 30 seconds until the door is opened? >
  
  I like to knock five times, in the pattern of The Terminator theme. >
  
  I like to rapidly hit my fingertips on the door, like if I was speed typing. Friends laugh and also always know it's me. Dosn't work well though on giant houses. >
  
  7 times for me. 
  Knock knock knock knock, knock knock knock. >
  
  4 knocks it's the drunk friend, 3 knocks is the neighbor, 2 knocks its your mother, 1 knock its the SWAT officer. >
  
  7+ knocks signals to the other to start singing to your beat >
  
  Buy drugs in South Dallas. The expectation is one knock, and it better be damn gentle or you're getting a pistol in the face before you get your dime sack. From one of eight dudes sitting on a couch (none of whom are the dude you came to see) all trying to compete for your $10.
  I never got used to it. >
  
  I have walk in rights to all of my friends homes, but if I'm going to knock,  it's a cop knock just to f**k with ya. >
  
  I believe according to lore, & i think this has also been depicted in movies, vampires knock once on the door when visiting homes. >
  
  Ikd I would punch my friends door 1 time and he would know it's me and answer lmfaoo >
  
  Used to call it the rock knock. One hard bang. No cop knocks once >
  
  Because one knock means you go straight from nothing to knocked. If you knock more than once, you are knocking >
  
  I used to work as public relations for a couple of companies, and by that yes I mean door knocker. At the end of the shifts I would do this, depending on what job it was and what I was promoting. Most of them didn't hear, but at least I could say I knocked. >

  To add to this, I have a 1-syllable name. When I put my name in on the waiting list of a restaurant I provide a 2- or 3-syllable name. When the name is called in a noisy environment it’s easier to discern than the short staccato of my name. >
  
  This is huge. >
