“Wai” is the standard form of greeting in Thailand. You put your hands together at chest height. The older the person who is being greeted, or the higher their social standing (monk, aristocrat, patron, important client), the higher the position in which the hands are held. To greet the king or to pay respect to a statue of Buddha, hands are raised right up to the forehead. According to custom, the younger person or the person of lower social standing should always “war” first. Monks are not required to return the greeting.
