general things...
Anything that intrests you.
Any two people can and should talk about whatever is of interest to both of them. There are a large number of potential topics. Personally, I like to talk about music.
Be really sexy
it means that you are in love or just want to talk
The answer depends on the girl, the boy, and the phone. If a boy has a question about homework or a sports team, there is no reason why he can't get the answer by calling a girl. When it comes to calling a girl just to talk, so long as both the boy and girl want to talk it should be appropriate, but their parents should pay attention that the conversations aren't inappropriate.
This depends on the boy. Your stereotypical boy will enjoy sports, or bashing on whatever teachers he may have if he doesn't like him/her. Books/movies is another safe topic. Or you could simply ask him want he wants to talk about.
The same way he talks to you face-to-face. And politely.
Usually you want to avoid the guy topics such as football and politics. When you're around a girl you want to talk about girl things such as hair, makeup, and girl tv shows. If your talking to a tom boy then it is okay to talk about guy stuff.
That means he likes you, but is embarrased to talk to you.
Bang her.
He might be embbarassed to be with u.
Go for it and just talk on the phone, use E-mail, or/and letters! Good Luck!
