How can you tell if they're flirting with you?

[Dole]

Dude, you're 15. Its supposed to be all uncertain and awkward. Just pretend you are in an episode of The Wonder Years. Come back to us in ten years for advice on what to do when your 'girlfriend' cannot stop shoving crack into every available orifice, and the bleakness of human existence has made you realise that 7" doesnt actually mean a whole lot. Especially when you realise that you have been mis-reading your ruler for all those years, and its actually 7cm.
