How do you know if a girl teen likes you Are there any signs?

Yes, there are signs. It all depends on the girl though. Some may be extremely flirty, almost to the point where it's annoying. You can ask one of your girl friends if you're not sure, because sometimes guys don't notice the obvious signs, while other girls can. If the girl is very shy, you will probably catch her looking at your a lot and then when you do, she will look away quickly. Or she will go to places where you are, and try to be near you in any way. The best way is to ask one of friends, she will most likely know.
