Well actually I do that for the girl I like, I really want to see her talk and smile, but I am too shy to do that very obviously.
Maybe that's what is going on his mind, he wants to see you but he's shy.Why don't ya try telling him hi next time he smiles at you, see what'll happen! ;)
if he tries to take your panties off i think its pretty obvious
If he keeps looking at you. Also if he tries anything possible to cheer you up or get you what you need (no matter how far out of his way) he has a crush on you. Or if he just tries to be around you. Ask your friends if they know he likes you. Sometimes unknowingly a guy will let it slip he likes a girl and it usually ends up at your friends. (I accidentaly told the bff of the girl i like that i have a crush on her, we just do it)
She likes you. Girls always want attention from the boy they like whether they make it overly obvious or not, if they make it obvious it just means they have a stronger personality and more determination.
yes and no...if he's a total stranger then maybe he likes you or it's just he tries hard to remember when and where did you met...
You belong with me
if he tries to show off in front of her
It could mean anything. Maybe you friend thinks you and your crush would be good together.
He has an interest in you and basically may have a crush or admires you ;)
Yes.
He tries to keep it secret for obvious reasons!
When tries to sell you products related to your obvious interest
hes got a crush on u or hes a stalker
