Thai People wash their feet when coming back home
Now that’s the only thing on the list that is strange but actually pretty cool. Whenever you come back to the room with a Thai girl, the first thing she does is run in the bathroom and wash her feet. “Feel better” is their standard response when you ask them why they do it but the main reason is that it comes from the perception of the feet as the lowest and most dirty part of the body (that’s why you should never put your feet up on a higher position as your head or even worse stand on a baht note as it has the king’s head on it) and that’s why they always try to keep them as clean as they can especially when coming from outside back to the room.
