Encounters like that, make it about the book. Don't even say your name, ask for hers, ask a question about anything other than the book until you know she doesn't mind talking. End of the convo put the ball in her court. " we have a book club at X on wed at 6:30, maybe you'd enjoy it. It was nice to meet you.....sandy. Hope ya have a good day. Nice meeting you" if she wants to give you her number she will then. If not, and she shows up at the book club, keep it light. Invite to a group event like a party. Then a date.

This does a few things:

A) zero pressure. Any personal info she gives is voluntary.

B) feel safer/ more relaxed. You come off interested in the book, not taking her pants off right there. She doesn't get a feeling of discomfort from you prying from the beginning. You just didn't pry at all.

C) voluntary. She wrote a number, real or fake, because she wanted to, not pressure to get you to leave. She came to book club because she wanted to, not cause you kidnapped her.

D) interested. You seem interested in something in her other than her vulva.

E) don't seem to care she's a girl. Seems you strike conversation for conversation sake and not strike a conversation because she's a girl. May get her intrigued that you are prepared to walk away with no name, number, or anything and didn't even try to. Shell feel like a interesting person and not an interesting pair of boobs and a vulva.

I don't even ask names from girls. I'll get a name when she wishes to give one. I don't ask questions outside the 'book' or piece that opened the convo until she opens that door herself. Really I just don't open doors period. As one girl told me, I seem 'mysterious', which makes me 'intriguing'. So I let them open that door too. Its not til they open whatever door first, that I'll use that door myself. She approaches first? Ill approach next time. Not only are they more comfortable when they do it them self, but you can see the trust build with each door. I can walk away with numbers i was gonna walk away from without or even asking. It works for me, but you may need to tweak it to fit you so it doesn't come off as fake.
