Input: Text: okay - so this happened earlier this week. i got off work and on my way home i was feeling a little frisky and decided to text someone who i hooked up with 2 weeks ago. they lived nearby the train station on my way home and said they were home, and told me to come over.

score. i shot a quick text saying i'd be over in 5 minutes.

here is where i fucked up. i decided to go to my hook up's apartment by memory instead of by rechecking the address. they live in an apartment building that sits next to an identical apartment building with the same architectural layout and apartment numbers. 

without checking the building number i walked in through the front door which was conveniently open, and raced up the steps two at a time and made it to - seemingly - my destination.

the door was left graciously open, i guess he was expecting me since i did tell him i would be there in 5 minutes. i welcomed myself into the apartment closed the door behind me and saw that the bedroom door was cracked open down the hall. 

i decided it would be a sexy idea to enter the bedroom in my underwear so i proceeded to kick off my sneakers and pull down my sweatpants to my ankles and call out, "hey i'm here, coming in."

as i'm about to lift my first ankle out of my sweatpants, out comes a lady from the bedroom and she gasps and i just stare at her wide eyed as my heart drops into my nutsack.

i forgot to mention - i met this dude on grindr (gay hook up app) and he had mentioned to me that he's married to a woman last time we hooked up.

the first thought that ran across my mind is "why would he invite me over when his fucking wife is home?!?!?!" i didn't know what to do, i'm sure i was only standing there for 10 seconds but it felt like an eternity of eye contact. i spit out the words "sorry i think im in the wrong apartment" yanked my sweats back up, grabbed my shoes, and ran out the front door, down the stairs and out the apartment building. 

i look down at my phone and see a text asking where i was and his address that stated 22-15. i looked at the apartment building i just left, it read 22-19 and the one beside me read 22-15. i facepalmed myself so hard. moral: ring doorbells and knock on doors before entering people's homes.
