How can you tell if a 10 year old boy likes a 10 year old girl?

You can tell if a ten year old boy like a ten year old girl by if he teases her or is VERY kind to her. If he ignores you, he probably isn't interested. If he pulls your hair, that is a sign that he likes you. If he a very kind and sweet he likes you. It really depends on the guy. He might just tell u (:
