I can't believe the narrow-minded nature of some of you plebs, you seem to be proud of not being able to speak thai. You ought to be ashamed. So what if it's not the big bad language that English or Spanish is that everyone speaks of.
If you're living in Thailand no matter what your 'style' is if you make an effort to speak 'decent' thai, (not the hooker bar variant either) people will respect you much more and when you're up shit creek with a broken down car, lost or arrested etc you won't be panicking about whats going on around you.
Sorry Dr Bob is that too much 'Big Time' Player style to you. I'll get back to my UN meetings now
