Hypothetically a very big problem

So, Person A has confirmed that she has a crush on Person B and he seems to lke her, but then Person C is being kinda weird and Person A's friends are being no help! Person B let Person A borrow some paper even though she didn't ask, he just noticed and decided to be nice, but another girl needed lined paper and was sitting on the other side of Person B and he didn't give her any paper. Person A thinks she's over analyzing what Person B does and is wondering if we really need boys or if they could just be sent to mars forever or something. Grrr.
