Re: How is this for an opener if girls are easily wierded out?
I don't agree with you about the U.S. vs english women. I have hung out a lot in London and did not find that to be the case.
In terms of your openers, it has more to do with congruence than context. Any opener should work if you are congruent with being a confident cool dude. Having said that though, you would open up with what you described. I'm not sure if that is a true story, but the structure of it, is an opinion opener... so that should be fine.
The world is your matrix. You control the strings.
