As I try to reach the upper echelons of high Thai society,Im trying to learn proper Thai,not the Thai spoken by go go boys.Although theres nothing wrong with it. Anyway,Im finding two different ways to say thank you,one is korp khun krap(cop coon crap),and the other is khob khun krub(cob coon crub) Why are there two different versions? IN one lesson the male says krub after just about everything.I realise its formal politeness but its very distracting. :scratch:
