You're lucky!
Well, if you don't like anyone then ignore them. If you like someone then you talk to them about it! If you're too nervous ask a friend to.
He is either interested in you or likes you!
What do you want to do?
look at him every once in a while see if he notices you see if you can catch him staring and you during a boring class
If a boy likes you be yourself. Don't try to be someone your not because he will think of you as a creep. If he likes you he will smile at you lots and want to be around you every minute of every day!
An ounce of of some class a weed and a nice pretty bong. No matter if he doesn't smoke he will like it every teenage boy likes weed.
He likes you back.
Usually if they tease you or they are mean to you.
Go up to him, and ask.
Glance around in class every once in a while and if you see someone that was looking at you they'll look away immediately then you just wait and see if they look again and make a nice blush. if he blushes you know he likes you.
From a School Counselor: Don't listen to anyone but the boy that you like. If boy B says he likes you tell boy B to tell boy A to come tell you himself. Never, never, never have a middle person because it always ends up bad! From me (the person who asked): what if you dont know if you like boy A or boy B and you're too scared to ask them if they like you?
He probably likes you... Smile back, if he approaches you, flirt Are you in the same class? If so pass a notes to him and he will eventually tell you how he feels.
It is usually a YES. But maybe he just likes showing off in front of all girls , to be sure observe his behavior in front of other girls. If it is the same then he may not like you , if it differs then he does.
