I have a friend - a fairly good looking single man. But I cannot explain him How should he behave when women are starring at him - without scaring them away...
I mean, he is often catching the unfamiliar women starring at him in the public places - parks, stores, busses, etc. And he doesn't understand What is he supposed to do:
- node and/or smile back? (in passive inactivity)
- wave at her? (which will embarrass her for sure!)
- treat the stare as an invitation to make a move - approach her
and strike up a conversation...)?
- look back at her and walk away. . .

Im interested in the female opinion, mainly, but guys are also welcome to post their takes on the subject!

Thanx to all of you!

I would think that if he smiles at the woman, and she smiles back, there would be no harm in approaching her and saying hello. However, it's not a given that it's an invitation. I think every situation is different.
