Don't get a bad impression of all chicks just because of one game playing manipulative immature attention seeker.
Yes, young chicks do play games more - they are inexperienced and they are testing their skills at controlling guys. It makes them feel immensely powerful when they discover they can do this at that age, so they play with it.
The problem is, if you start playing games back by ignoring her, so that she then comes running back, when you finally give attention she will then turn her back again. It spirals out of control and goes nowhere.
Be warned it can lead to oneitis and you don't want that, so don't fall for these games. Cut through the BS, make a move - get her on a one on one date, kiss her on the lips. Take it from there. If she won't do any of those things, she's wasting your time.
