Hell no! Look them in the eye. I am no shrinking violet. If a man can't look me in the eye then my perception of him is that he is shifty, he has something to hide or a secret agenda. If you are talking to me look me in the eye. Then I know that I have your attention. I don't have time for demure flirting games where I avert my gaze. But some men when you look at them see it as confrontational that happened once and it scary because the man was on drugs. and later flipped out.
