The third-floor murals inside Phra Mahathat Kaen Nakhon stupa at Wat Nong Wang temple show kalam (คะลำ), an Isan word meaning "things people should not do." Many of these social rules are about showing proper respect to those with higher status than you, but others cover safety, manners, etc. Even traditions that the modern age has made obsolete, such as #27 (because most houses now have electric lights), are still followed by some people. But as me-first attitudes arise in Thailand, many people no longer respect these rules. Thirty-two kalam were painted here so the next generation can learn them and the current generation doesn't forget where it came from.
