  That’s what most people are missing it seems. In OP’s case it was 2 hours after the meal.
context: Your family' forcing you to stay sitting even when you have to shit? >
  
  For many people, shitting while standing is a problem. >
  
  You would like my family. We never really did the formal thing. >
  
  everyone stays at the table? My extended family just wander everywhere unless they're drinking. >
  
  Same, but I have been to dinner where everyone sits. >
  
  Why do so many people on Reddit have problems setting boundaries? Just get the fuck up, no one is going to physically stop you. >
  
  Seriously. 
  I'm a 28 year old adult.  I have a job.  I own a home.  I have a life and hobbies. 
  No one is going to "force" me to sit at the table after I'm done.  I'm not a child. 
  I know staying to chat is a social norm and a societal thing, but anyone who's ever been around me knows it isn't my thing. 
  I've never even had someone bad an eye when I've gotten up from the table to get some space. 
  On the rare occasion, I've had someone who doesn't know ask if I was okay, but it was out of concern, because getting up and leaving like that isn't normal, but I get that and I appreciate the misplaced concern. >
  
  Literally all you have to do is say "Hey I'm gonna head out, nice to see everyone!"
  People who are passive like OP piss me off. >
  
  My dad did what youre saying, he would just get up and head into the kitchen or whatever at family events, still 'in the room' but not at the table. We didnt have family dinners outside of holidays so we never had that etiquitte really, but I can KIND OF see how if theres some event and a dude comes over for food and he sits down, eats and then after a bit goes, 'alright well Im bored, I think Ill dip, nice to see you thanks for lunch!' would be pretty offensive. 
  I know you mean to say have some tact, but you made me realize why that 'social rule' exists in the first place. >
  
  That's the thing though, it shouldn't be taken as offensive. Just because someone has cooked another person a meal doesn't mean they should be obliged to stay if they don't want to. That person may very well be happy to reciprocate the gesture by cooking for them but they may be an introvert and not really like socialising for any length of time.
  If someone gets offended because of that, they're not worth being friends with. >
  
  The thing is if you come over someone’s house just to eat and then immediately leave when you’re done eating, it makes it seem like you didn’t care about their company at all and was just in it for the food, which is rude and disrespectful. 
  It’s just social etiquette to stay a little while to show appreciation for the hosts. >
  
  You would like my family. We never really did  the formal thing. We just get the food buffet style, sit where we want, eat, and then go about our business or play games or go for a walk. No awkward small talks. >
  
  Who is forcing you to stay? Just get up and go. Say you need to stretch your legs, are too hot, got to have a shit, whatever. I don't get this one. >
  
  I think OP is a literal child, between 12 to 15.
  EDIT:
  
  But my comment was not that I have to stay. It was more a comment about how I am of the opinion that when everyone is done with their meal, that people should move on to cleaning/using the restroom/stretch your legs/continuing the conversation elsewhere.
  That's it. It has nothing to do with being a child vs. adult.
  
  Maybe not? Confused now. Still sounds like a kid trying to preach to adults. >
  
  Ah, ok. In that case, OP, ask your parents if you can leave the table. Or offer to start clearing up. And then you'll just have to do what they say. >
  
  An hour is my limit.  I'm happy to engage in small talk for that amount of time, but at some point it's enough.  And sitting at the table isn't even comfortable. >
  
  An hour? That's not even a business lunch here. More like 4-6 hours of family meal over here. But you don't sit the whole time (e.g. dance, small walk, form different groups in different areas of the house, etc.). People are only really together when making a speech/toast. Otherwise everybody's all over the place.
  Also, family Christmas dinner is like 90-120 people, so you're never bored. >
  
  My hour meant an hour in addition to the time at the table to eat and the inevitable time before that.  At a family meal, of course it ends up being lengthy, so my hour means the time from the last bite of dessert.  
  Keep in mind that it's not really about boredom or not.  Some people don't want that amount of stimulation and want some quiet time or to switch to another activity.
