There was a big mix up when my daughter moved into her dorm room, so instead of moving in at noon, she didn’t move in until 5. By then, the other 3 kids and their parents had moved everything into the common areas (each girl had a single room and they shared a common room, kitchenette, and bathrooms). There was one (pre-assigned) cabinet in the kitchen for my daughter, but every single inch of the rest of the suite was taken - shelving and twinkle lights and chairs and a TV cabinet/TV/video gaming. Rugs and posters and decorations were all up. They’d even hung a row of Command strips down the hallway to hang up their lacrosse sticks. My daughter had her room and her cabinet.
My daughter is a minimalist. She didn’t care that the others took over every inch, decided on the colors, bought all the kitchen stuff. They did not ask her to pay for any of it. About half way through the year one girl got huffy and took all her stuff, including the toaster, into her room. And they all lived.
ALL the others, even the huffy girl, asked my daughter to be roommates the next year. D is no fuss, clean, and likes to bake. Perfect roommate.
