Why is it some men get all offended if a woman they don't know is wary around them?

53. Heh..been there,done that and I have perfected the stare

Which is one of the reasons when I go on a smoke break at work I choose to stand and not sit.
Much easier to control my comfort zone with those who feel a need to approach me and stand alittletooclose or start with a casual hi and ends with kind of a stalkerish tone ("so when do you work next? What days? What shift? What floor do you work on? You drive or take the train", "how come you never sit down when you come down here, you're always standing up&quot .
Which are questions I wouldn't care about if they are asked by someone who I am a regular talker with or a close co-worker but when they are asked by someone I have never even talked to before....it makes me nervous.
One time I was in a particular "I don't wanna talk to anyone" mood so I went straight from the building to stand behind a little brick wall and one fellow I didn't know felt a need to pop around the corner and literally said "ah-ha, you thought you could hide, huh?" and then seemed kinda stood there talking with an amused look on his face that he had came and made sure I knew that he had "found me".

I'm really not anti-social but there are some situations that get me in flight mode very quickly...if that turns off some people who approach me, TOO BAD!
