No roommates. Live with my parents. When I had roommates, one year we were best friends and never had a single fight because she was the most easygoing person ever (both of us are), and the next year we both just kept to ourselves and inhabited separate universes.
I actually blathered something like this (feel free to cringe for me... it's awful!):
Me: (panicking, I don't have conflicts with friends, my friends are a very low-drama bunch, and I'm usually the mediator/conflict resolver of the bunch.... I'm also really easygoing and really don't remember fighting with anyone) Ummmmm.....well my sister always throws these crazy parties and trashes the house. And....umm.... sometimes we get into fights about it. So yeah....
Him: -looks quizzically-
Me: Actually, I have a better one. My boyfriend and I had a conflict when he joined a frat and had a lot less time for me. I eventually thought it over and asked myself: "Is this really something to be mad over? Isn't our relationship otherwise very healthy? What am I really worried about?" I realized that it was a trivial reason to get upset with him and then played some hard to get [laughs], no, I mean it, it worked! It made him want to talk to me more! But actually, I'm a pretty easygoing person and I always think through situations and usually determine that getting upset is inappropriate. I wind up talking it through with them, as it's really important to understand the other person's point of view. But If I still think I'm right, I just come up with a better argument. (laughs).
FACEPALM. Auto-rejection right there.
