I can’t speak for your room mate, but I can speak for myself. I was introverted as fuck during college and spent all my hours between classes in my dorm room. Thankfully, my room mate was the same. We each kept to ourselves, listened to our own music with headphones on, and save for a few quick and infrequent phrases, never communicated with each other. She minded her own business, and I minded my own business.

I would have been annoyed as fuck to live with a social butterfly, considering my low level of tolerance for small talk back then. Silence is only uncomfortable if one party chooses for it to be.

I wasn’t depressed or crazy. My idea of fun was my homework and my side projects, both of which were solitary activities. My idea of fun was NOT eating dinner with some rando and have a discussion about the weather or color or the floor. I would have been pissed as fuck about having a preppy girl of a roommate resent me for not sharing the same values as her. Some people are quiet and private, and if they can’t even do that in their own room, then where do you suggest they do it?

I don’t see why you need to be friendly with your roommate any more than you would need to be on speaking terms with a rock. As long as the roommate isn’t unhygienic, making a mess, making a racket, or in some way actively interfering with your life, then what’s the problem? Let and let live.
