Input: Text: so i meet this guy in a gaybar, he comes back to my place.  
the sex was pretty allright, afterwards he's in my bed almost asleep.   
that's when i see it.   
my favorite white armchair ruined by a chocolate brown stain.   
he was the only one to sit there (naked), it was definitely him.  
so first i tried to ignore it, he didn't seem to notice.  
but then while he cuddled up to me i started thinking about the shit stain and my favorite white armchair and i just couldn't take it anymore.  
i kicked him out, he denied it but went on his way. 
i heard de door slam and thought it was finally over.  
but no, god really wanted to make clear that he doesn't like homosexual sex by letting this guy forget his wallet.  
fml.

TIFU: by having a one night stand.
