Oh dear. Another one of these arguments where both sides are equally wrong. Like the debate about fascism.

On the one hand, if a bird asks you for directions and you come out with some sleazeball line about her flirting with you, you'll come across as a massive creep. On the other hand, if you don't at least engage an attractive woman who approaches you in case she's married or something, have a nice time with Mrs Palm and her 5 sisters.

Look. There's nothing wrong with chatting up any attractive woman whenever the opportunity arises. Read the situation - if she's obviously in a hurry, let her go. If not, have a conversation with her. Flirt a bit, if time allows. Tell her you should meet up later and get her number. At the moment I have a big strop with people who are saying things that equate to, "Well I'm so alpha, and living in such abundance, that I don't need to make an effort - the birds should come to me". Rubbish. Put yourself out there and take some risks.
