If a woman was to show interest in you, would you know what to do? What would you do?

I wouldn't know what to do or how to react to captivate and enhance her interest and instead would probably pretend not to notice and make up a way to get away. I'd find it very difficult to see an approach by a woman as genuine interest based on past experiences with some of them. Women regard approaches by men as perverted stalking bordering on sexual harassment.
