He is probably just messing with you. Seeing if he can get a rise out of you.
It means they are ill mannered and were'nt raised appropriately. It also means steer clear of these bozos.
either they are sizing you up, or they are seeing what you look like to see if he wants to date you. Those are my guesses.
You got stuff in your teeth
he probably likes you and gets nervous when you discover he's staring at you OR he was surprised to see you staring at HIM.
if he stares at you (not glaring) or seems to always be staring at you. if he gets nervous around you that's bout it
Chances are he's shy and if you like him and you notice he is staring at you and frequently gets near you, he is hoping to spark a conversation. if i were you i would approach him and just create small talk.
It means he likes you.
Because the butt never gets exercised.
no
of coarse
She needs to cry.
he might like you
He is obviously shy. He is staring at you because he likes you and when you get near he gets embarrassed and he is afraid to talk to you. Maybe he has been rejected often and is afraid that you will reject him. He probably looks at you like you are too good. If you like him you should make the first move, it will be easier for him and it will boost his self esteem.
no it does not get bigger
your butt gets bigger
