Greet him casually like you would do with your friends. If you don't know him to well, get to know him while you're at it.
Go up to him and say hi
It goes like this... "Hi!" and he says ... "Hey!" piece of cake
say hi
Well first you need to know if he is a nice guy. If he is your chances are that if you walk bye and randommaly say hi, he will say hi back. If he's mean he might not say hi back because he doesn't know you.
Because he likes you sillly! if you say Hi to him he will know you have noticed!!:)
be nice to him say nice things to him like hi and bye
guys hit each other to say hi, idk why. but why would u do that ? probably, i will feel bad or annoyed, or sumthing, if someone said hi to someone n not me. idk why. but probably. n more if he stares at u, its like saying "Arent u going to say hi to me too?" Well my answer is Proabably yes.
Say, "Hi, you're cute! Want to go out sometime?"
Hi! Im quite taken by you. are you interested in going out with me tommorrow?
" Hi, I like you." Then you run. As fast as you can, and if they chase you back then they like you also.
Say hi back!
He prob likes you, but is just too embarresed to admit it.
