My campus routinely had a small number of students who signed up for a dorm room but then never showed up to claim it. For that reason, they regularly would "triple" some of the dorm assignments (assign a third person to a two-person room) for the first week of class. As they confirmed the no-shows, they would move the third person into that open space. I was the unlucky "triple" when I first moved into the dorm, and slept on a mattress on the floor between the two beds of the permanent residents. We knew it was just for a week, so we were all extra accommodating.
My two temporary roommates couldn't be more different. One was a polo-and-pearls super-prep, her hair cut in a smooth beige bob. Everything about her was tightly controlled from her schedule to her voice to her food. The other was a grunge rocker chic with long wild curly hair. She wore ripped jeans and a studded leather jacket, roared with laughter at her own dirty jokes, drank like a fish, and rode around town on the back of her boyfriends motorcycle. I was somewhere in the middle of these two extremes.
By the third day, each of them had approached me privately to beg me to stay in the room and help them move the other one out. But that was not in the cards. I got my permanent room assignment at the end of the week and moved out. But I stayed friendly with both of these mismatched roommates and saw the strangest thing happen: as they got to know each other on a deeper level, they grew to appreciate each other and became quite close. The prepster loosened up a bit and the rocker chic polished up a few rough edges. They didn't morph into identical twins, but they each evolved a little and found a lifelong friend.
Immerse yourself in your colony sisters, especially the ones that you don't think you have much in common with. You may get a fabulous surprise.
