she's shy to look you in the eye
He likes you.
This could mean many, many things. She might like you, sure, that's a chance. She may also be interested in your dress sense, but not you personally. She may find something on you physically intriguing, but that doesn't mean she likes you. The only way to know is to ask her. If you don't ask, you don't get.
Is she stares at you and then continues to stare at you when you look at her, she may be crushing on you.
most likely
Take it from me. I mean it depends how the guy is looking at you. Is he looking at you in astrange way or in a gazing way i like her.If you feel he's looking at you in a i like you way he must like you, but a guy that askes to do his homework. well you might want to find out if he's good at the subject if he is then he's totally into u. but don't go straight up to him.
She keeps looking at you when your not looking.
He wants to get in your pants.
if in class he keeps looking at you and he always starts the conversations then he most probably loves you
Keeps on moving
that means he probably want to go out with you
That means that that boy likes you.
ifthat guy teases you or pulls on you hair, stares at you, then there is a 90% chance he likes you...and if he hugged you 99%
