But they weren't wings. They were guys from work who stayed back and watched nervously while you went and approached.

And a wing in a one set doesn't really work - three's a crowd, and all that.

A wing would have joined you in the conversation after a short while if there were other girls around, and helped take care of them. I'm not saying its uniform, and that every good PUA needs a wing. Plenty do perfectly well on their own.

But for me, I find it helps.
