I think Im going to talk to her directly and see what she says. Ive never been to a hookah bar before. I know, I feel so prudish! I guess we could try that together if she doesnt mind that sort of a thing. :)
Hmmm...why do you feel prudish? You are who you are, and she is who she is. Simply tell her you're not interested in doing stupid things...let her think you to be a prude or whatnot, but you have your values and principles and you should never shy away from them for fear of what others think. And it's a-okay to doggedly stick to those principles...if she's not willing to tone it down for you, then move on...plenty of people out there to be friends with!
I knew a similar kind of person. She lived in an apartment sponsored by a Muslim charity, had a conservative family, but dated, drank, and the whole nine yards. I dunno...I found that rather scummy...her life is being subsidized by religious people, and here she is doing all of that without any qualms...blah...
