So I've gone on a couple dates with this girl, she's legitimacy ridiculously good looking (if looks were an SAT score she'd have a 2400). Anyway she suggested some activity with her friends and I snap accepted.

This seems pretty tricky because:
1) Pretty early in dating process, don't want to be too affectionate since this could seem desperate/clueless.
2) Girl's friends will probably be searching me for problems the whole time.

My plan is to just:
a) Make a confident first impression, take the initiative introducing myself and asking names.
b) About half the time, be talking to one of the girls (talk to everyone about equally), half of the time listening.
c) Some subtle DHV built into storytelling, but definitely nothing that seems like i'm trying to impress/show off.
d) Just be casual/relaxed in general.

Any tips? Seems like a much easier thing to mess up, kind of a make or break situation.
