Well as in all languages what we first seek to know how to say is the usual platitudes. Saying hello, asking the other how it goes, what's his name, also giving our surname so here is how you deal with that in thaï language for a conversation between me (yes, I am egocentric and then?) and women :

- Sawatdi krap
Hello

- Sawatdi. Sabaïdi maï kha.
Hello. how are you?

- Sabaidi. Khun la krap
I'm fine ! And you?

- Sabaidi. Di chan chue Lia. Khun chue a-raï kha?
I'm fine. My name is Lia. And you, what's your name?

- Pom Chue Michael. Pom bpen kon farangséet
My name is Michael. I am French.

Well, this is a start. If you get understood it is well!
