I'm an anglo saxon in singapore, a nd travel a heap.....especially in SE Asia.
I am an Australian by birth, and I think that the basics "hello, goodbye, how much? No thank you, Where are the toilets?" These you should know in any country you go to. I have no facility in language, and often there is an english speaker who can help, but my BEST advice? Just go for it! Be brave! Be bold! Try, butcher the language and be able to laugh at your bad BAD language and order heaps of beer...
