"The Line" QUESTIONS

Wrestling Boxing Day, I'm coming out of a convenience store. A young woman is coming in, so I hold the door open for her. A young man, coming from a different direction, follows her in, saying "Ummm, sexy THAT!"

This led me to posit several questions:
1) Was he talking to her, or more to the universe at large?
2) Was she offended, delighted or what? (I was waiting for a bus, and I could have gone and asked her, but thought the better of it.)
3) Does that kind of line actually work on some people?

I never had a "line", as far as I am aware. Sometimes I would do stuff (throw peanuts in someone's beer, play air guitar), but smooth talking, I didn't do.

So, I'd like you to answer question #3 above (and #1 and/or #2, if you have some insight). Additionally, I'd be interested in what kind of lines you've tried, and whether any of them actually worked.

I'm interested to know your gender, approximate age, and sexual orientation to see if it differs.
