I think that all depends on the individual boy. It doesn't matter if your a boy or a girl, some like people that talk a lot and others enjoy people with few words. The key is to find someone that you can relate to and not how much they are or not saying.
Depends on the boy of course. I've found people enjoy questions about themselves and that what they really like is to be listened to. Most people forget that the most important part of communication is listening. If you want a boy to like you, just be yourself. If you're chatty, be polite and don't just talk about yourself. No one likes that. People DO like to be talked to of course, so find your personal way of getting to know others.
Yes boys like girls who are talkative. Teenage boys are a little shy so a talkative girl can really help. Just don't focus the conversation totally on you. I am older and own my own construction company. My wife runs the office. She likes me to call her on the way home. She can talk nonstop for an hour and a half some days. I know she has been in the office alone all day so I let her. Truth be known, some days I would just like to sit back, drive and listen to music on the radio.
