How do you tell if a thirteen year old boy likes you?

If a 13 year old girl likes you she will play with her hair. Some girls will rub one leg on the other one. Most of the time she will immediately text/comment/call you back.She if she "just happens to" be by your locker alot. At lunch, casually see if you see her smiling or looking at you. The Girl will also laugh at alot of the corny jokes you tell. If she likes you, she won't wait forever so ask her to be your girlfriend. the worst thing she can say is no.:-)
