I don’t mean to be rude, but have you got Asperger’s?, can’t you read social cues and female body language?, it’s not rocket science.
If a woman is giving you death stares, dirty looks, it’s her non verbal way of saying “go away creep, I don’t like you”, where you should make a very rapid exit. And no I don’t grab the arse of a woman, unless she lets me.
Get it through your head, that women make snap judgments on men based on what they see, and if they don’t like what they see, it’s game over, lights out.
