My 1 cent of observation :
Going out in group is, I agree its a Thai thing...not just for lady night but for most Thai girls. They somehow want their good friends (meaning their good friends, not colleagues) to take a look at the guy and later on they can gossip what they think of the guy

They somehow like their friends to know who they are going out with...

It's also quite ok for some of them not to reply sms...but if they are using Blackberry (a Thai craze thing) then they are more likely to reply readily. And if they dun (even though it's a Thai craze thing), then do not have high expectation of them replying sms readily, fast and furious like we are used to it here. My ex gf used to reply a few and then get fed up and call instead

Some of them just dun like it (Thai language is a tonal language, it's hard for them to express things in alphabets at times without the tones) ...observe if she uses Internet frequently...those who dun are unlikely to be inclined to sms stuff.
Well, I am also in the process of learning, de-learning and re learning about them...but good thing is I have Thai friends in BKK whom I got to know in the course of work and they are all so ready to explain to me the differences in culture...so now whatever I dun understand, "I look at it with an empty mind and ask a Thai! "
Dun be surprised, they bring you to fortune teller and ask fortune teller if you are the one for her

or before you meet her parents, her parents already know so much about you...and when these happen, go with the flow and dun be angry, cause they will feel hurt and paiseh if you do it in front of her friends and parents..talk to her privately for such issues
