There isn't much you can do but be as nice as possible to both him and his friends, look at him occasionally and flirt. Other than that there is nothing you can do if he doesn't like you.
Then he knows.
He stays away from you
It means he knows you like him. It's how he comes across that matters.
ask him out if your feeling brave
Nobody knows.
It means he likes you back, or he knows you like him, so he tells his friend.
you try to make him jealouse
it means he has a pet rat
Yeah a boy can like a girl even if they aren't dating. I like a boy and we aren't dating... maybe she even likes you back. Who knows?
just keep it cool and pretend like he never knew
Take a chance! Who knows...
i think that it means this boy likes you back but he does not want you to know but i am not so sure
