if you listen to her when she talks, it will show you are interested. Also if your listening to her your not talking about yourself which is a good thing.
Don't ask me for relationship adivce, i'm nearly 17 and have never had a girlfriend. I was once asked out by a 'girl' who turne out to be some of my 'friends' playing a 'prank' The be yourself and listen stuff apparently works, though it never has for me. Still, your 13, if it doesn't work, learn an move on. You'll learn what to do and what not to do, often the hard way. Also... don't stare at her breasts or ***
lol its not nearly as hard to meet a girl as ya all make it out 2. im a girl and id much rather have a guy who can install my ram than throw a football.
At least there's on girl in the world who thinks like that I don't know why we do it, theres just some need to impress. It's the stupidest instinct know to man (and woman)
