In Khmer culture a persons head is believed to contain the persons soul therefore making it taboo to touch or point your feet at it. It is also considered to be extremely disrespectful to point or sleep with your feet pointing at a person, as the feet are the lowest part of the body and are considered to be impure. When greeting people or to show respect in Cambodia people do the "sampeah" gesture, identical to the Thai wai and similar to the Indian namaste.


Customary Cambodian teachings include: that if a person does not wake up before sunrise he is lazy; you have to tell your parents or elders where you are going and what time you are coming back home; close doors gently, otherwise you have a bad temper; sit with your legs straight down and not crossed (crossing your legs shows that you are an impolite person); and always let other people talk more than you.
