PDD Women complain about two things; that their politeness is constantly misinterpreted as flirting or that their "obvious" hints fly over the heads of men they were flirting with.

Flirting is obviously murky and ambiguous one girls platonic friendliness is another girls subtle communication of interest, but in this thread I want it to hear from women; when you're around a guy you find attractive enough to flirt with, what do you do? What are the most clear examples that separate it from mere friendliness?
