You have answered your own question. He is trying to get your attention.
Maybe if the boy/girl keeps on looking at you. Or maybe the boy/girl gives you stuff or gives you attention. Or the boy/girl talks to you a lot.
ya
Why? Because they like them, silly. Or, they like attention.
He is wanting your attention , its your choice weather to give the attention or not . If you choose to he might get interessted in you , or if you dont he might either keep trying or not bother
well it depends who or what the boy is paying attention to instead of girls...
Yes.
Tell him you like him.
Either blow him a kiss or look away
Most definately.
Be patient. The boy won't like you if you start to intrude. As soon as you have the chance, then try to get his attention.
Cry. they will join you and cry with you. it will be like a party.
