Re: I can't get a read
The girl was most likely there with a guy and felt it was awkward seeing the guy there at the show with another guy. She wants you there at the party because she likes you - go to the party hit on her friends because you have comfort with them since you know her friend.
Yes there is a likely hood she will say yes but she wants a guy to "know" when to kiss her. With more sexually open girls (onetaste) you can ask them and it is perfectly fine its just the way that community is cultured.
Looking for new wings in LA let me know if you want to sarge together.
