He is shy and checking you out :-O
He's just shy. I bet if you're a little outgoing, you can get him to open up a lot.
How do you know he "likes" you then? <br />
But if it's true, it's probably that you're both too young and uncomfortable with that. Just be friends with lots of kids .. works out better at your age.
If he likes you, he would SHOW you. End of story.
Put your pants down to your ankles and take a shi* in a public park infront of everyone. That always helps me think.
