Do women not talk with each other about what "signals" they use to express interest?

[Pohjolan]

There is a considerable overlap between the behaviour of interested and non-interested women from a males perspective, so are women just oblivious of the behaviour of other women?

Do you mean like flirting? No it really isn't a topic of conversation among friends or anything like that. We don't have a weekly meeting to discuss flirting techniques we all use. Don't have to really. I can tell when a girl is flirting. That is probably from the years now that I have bartended. You see just about every approach possible. It isn't really hard to pick up on for me. Some people are more subtle than others but even those types you can kinda tell what they are up to.

Flirting yes. Its not making a move if one doesn't risk getting rejected.
