Weiss wasn't used to sharing things.

Growing up, she never had to share anything. If she or one of her siblings wanted something another had, they were simply given a new one. Why bother sharing when you could buy anything you wanted?

So when Ruby hopped onto Weiss's bed to play one of her games, Weiss was surprised that it didn't bother her. It had been an exhausting day; Weiss couldn't blame Ruby for not wanting to climb up to her own bunk.

Weiss didn't mind sharing her things with Ruby at all. She knew Ruby would do the same.
