MY ROOMMATE ALLY and I are not exactly opposites, but we’re quite different:
I generally like going out with people and will try my best to go, even if I’m broke or need to be doing other things.
She’ll generally make up any excuse not to go out, even if she just won the lottery and has nothing to do but read. Books are her best friends.
I like meat. She likes pasta.
I like Ron Swanson. She likes Leslie Knope. (RIP, “Parks and Recreation.”)
You get the point.
