I'm slow when it comes to that sort of thing. If I suspect they're flirting, they're being pretty darned obvious.
For me it's rather easy....if she's a pretty female she's definitely not flirting with me!!<br />
Now larger black women? They wanna soak me up wit a biscuit.....mmmmhmmm *head bob*
They get a gleam in their eye, move closer, and smile.
I have trouble telling unless they're overly confident and ask for my number or something.
I tend to think they are just friendly. You really have to draw me a map to get it. Quite obtuse.
For example, one woman approached me and asked if I was ******* anybody that night. That was a fairly unambiguous signal. Short of that, however, there's plenty of room for me to draw the wrong inference.
