Do try to curb your body language: Thais may smile a lot, but they use body language far more subtly than Westerners and many other people do. If you wave your arms about or waggle your head around, Thais will consider it a puad hua – a headache – to look at. In Thai culture one keeps one’s feelings – of love or hate, enthusiasm or boredom – to oneself. Thais believe that you will have fewer problems this way.
