Flirting vs. Talking?
I'm going to be a bit of a rude boy here (but I'm allowed, it's our manhood we're talking about) and say this:
If you want to get with the chick it's flirting, if you want to get the study assignment it's talking. If you find yourself not knowing what to say next or feel like you should throw in some "cool" one-liners here and there, it's flirting. If at any moment you find yourself thinking of any excuse to go talk to someone else it's talking.
Turning on your "radar" to tell if a girl is talking or flirting, observe the following within the conversation:
1. Is she talking about things that she would talk about with anyone (generic questions) or is she asking you things about yourself?
2. Does she go out of her way to speak with you?
3. Does she make eye-contact?
4. Does she have her hand on your knee?
5. Does she have "the look"?
If the answer to all of these questions is YES, by all means RUN AWAY.
If, however, you can only answer "yes" to a few of these questions, then you're "in the game" and should pursue it as much as you like, this would indeed be flirting.
If the answer is "no" to all of these questions, the girl "ain't all that anyway" and should be kicked to the curb.
