How so 13 year old girls attract13 year old boys?

Well, this coming from a girl, boys should probably just give girls compliments and be sweet and FUNNY. Most girls love any guy who is nice and humorous as well. But this can come off as just being friendly, so try to drop hints if you want to be more than that. I'm sure you can figure out ways to do that by yourself, just be creative! Always make eye contact with a girl and saying things like she smells nice or has a really nice smile will probably give her the impression that you like her as more than a friend. Yeah, and stay as down-to-earth as possible.
