babe the first word for u :)
Hi=Sawasdee krub
for Thailand people, boys say" khub" but girls say "kaa" . so, it's different a little ;)
It's polite word.
but: Sawasdee by you don't say "krub" when end of a sentence,
you can say with only your friends or younger than you.
"Krub(B), Kaa(G) Thai" it's same" yes
