What does it mean when a guy just looks at you?
It could mean a variety of things such as he is interested in you, it could be coincidence that he is looking in your direction but in a daze and not really looking at you, or for whatever reason of his own.
he is probably either looking at your test and trying to get some answers, or he likes you, or he's just daydreaming maybe. when a guy looks at you in that situation don't jump at it and thin "OH he likes me"! A guy likes you if he: stares at you, smiles to you alot, looks at you in the hallways at school or just talks to his friends about you
