A final area to be careful about is body language, including gestures. Is it acceptable to touch a person on the shoulder? How do you wave goodbye or hello? How do you gesture to someone to "come here"? All of these can be different from one culture to another. In Thailand, it is rude to touch someone on the head with the palm of the hand. The gesture for "come heere" in the U.S. is only used for calling animals in some other countries.
