Wai Kru was definitely the most interesting experience in Thailand. It is a beautiful ceremony, with monk chant praying, incense, and flowers everywhere. The children crawl up to the teachers on their knees, heads down, almost like the Thai people do when approaching members of the royal family, and presented them with flowers. It is a surreal experience, and even feeling a bit solemn in some ways. Thai children have so much respect for their teachers. It is a very impressive ceremony.
