The foot is considered to be "dirty" by Thais. It is the lowest part of the body. Never point your foot (especially the bottom of the foot) at someone, refer to it or draw attention to it unnecessarily. Never move anything with your foot or step over someone if they are sitting on the floor. Sit cross-legged or fold your legs to the side, when sitting on the floor. Do not sit with your legs extended out in front of you. Always remove your shoes before entering a house.
