Have you tried talking to them about it? That’s not meant to sound harsh or snarky, but genuine. Some people don’t know when they’re being exclusionary, maybe?
I have tried talking to the guy who’s head of the house. I voiced my concerns to him, but he wasn’t very helpful. It’s really difficult trying to talk to so many guys though. There are 7 other guys I have to live with in this house, which is a very intimidating number.
