I always think it's just nice to start out by offering the girl
help. Depends on situation. Like in a book store, the girl needs
help to get something, just gelp her bring it down or whatever. Or
maybe if the some girl seems lost or whatever, just be kind and ask
where she's going. Not saying that by helping the girl, it entitles
the guy to spend a night with her, just that it's an opening.
Besides, I think it's just nice to help ppl out if you can. Just be
nice. I'm sure some chance will come. And if nothing comes out of
it, oh well, it was most of all, a good deed done by you.
