Is OTHER wrong in the post ? POST : I'm a college student and I live in a house with 3 of my male friends.  Two of my roommates have girlfriends that basically live here.  They stay here every night, they eat our food, use our wifi, drink our beer, use our shower, etc.  I've jokingly asked them if they're going to chip in on the rent and other bills a few times.  Their excuse is always that they don't actually live here so they shouldn't have to pay.  To me it seems unfair to split the bills between 4 people when there is 6 people living here.  AITA?
