Just walk up and tell him that he is going to date you soon, and when he gives you odd looks. Shrug and say, just warning you. Then wall away, nothing better then leaving someone freaked out and curious why you said something like that.
Don't do it. I approached a girl once, and it was the worst mistake of my life!
Throw a pencil at his head and see if the point sticks.. if it does ..surely you will have his attention ;-)
Throw an eraser at him. If he asks why you did it, just reply with the first thing on your mind.
I really don't know. My subconsciousness just loves creating constructive circumstances
Give him a note with your number on it.
nope and no way you're at least 18 and can't talk to someone...
