Hello I've got a very simple question. I'm still in high school, and I have limited experience in the dating world. Teenage girls these days tend to be very flirty - casually flirty. The way that straight girls tend to tease and joke around with each other, but I can never tell when someone might actually be serious about it. How can I tell if a girl is actually flirting, or just playing around? There are few things more embarrassing than getting your signals mixed up, and acting accordingly. Any and all advice is very much appreciated - Arli
