She could be a bit nervous talking to a guy in general , she could have a crush on the guy she is talking to so she looks down , or there is something interesting on the floor
Maybe because your a guy and every normal guy loves breasts, but i really think you shouldn't do this if your in a conversation with a girl, they like guys who look at their face when they are talking to them not the guy looking at their breasts.
He is enjoying the freedom of choices and not being tied down.
When he stops talking to you/looking at you
lots of ways but it can depend on the age of the guy. how old are we talking about?
look 4 the other hot, nice, cool girls and make friends! its not that hard! girls enjoy talking to boys :]
It is probably because the guy is staring at the girls cleavage or he doesn't care what she has to say he just wants to do her.
what do you mean "looking over"?
Girls like both guys who are good looking and guys who are not good looking. It depends on the girl, and the guy, and both of their personalities. A girl who doesn't care about looks can like a guy who isn't good looking but has a great personality.
Girls 10-12 shouldn't be looking for anything in a guy, because they're way too young to be dating.
it means he's a straight male most likely looking for a potential partner.
Most girls (the ones looking for a serious relationship anyway) don't care about looks. They want a guy who is nice to them and their friends, who doesn't ignore them or abuse them for that matter and someone who isn't always bragging or talking about themselves.
Depends on the intent, but it could be. If he is talking to a girl but is constantly looking at you, then he's thinking about you and not the girl.
