Let's say I'm male and I see a girl I like on the street, or sitting alone in a cafe/bar. How weird would it be for her if, out of blue, I would start chatting with her (in a non-creepy manner). Usually I have been introduced to girls through friends but have never tried any sort of street-pick up. Does it work at all and if so what's the best way to pull this off? I live in central Europe so people here don't do it as much as in America.
