How to flirt like you're not an asshole

(I posted this as a comment in a thread at ABW and figured I'd repost it here.)

Today I had a streetside flirtation that worked wonderfully, because the guy flirting with me carefully demonstrated that how much he’d give me was up to *me*. It was wonderful. He didn’t smile until I made eye contact, didn’t say anything until I smiled back, and when I broke eye contact and went back to what I’d been doing, he stopped.

If my dance card wasn’t totally full, I might have asked him for his phone number. Because unlike all the street harassment I’ve received — much on that very same downtown street — he wasn’t interested in demonstrating his power-over at me.
