Schools usually have a ceremony in the morning for the student body to “wai kru” together. The teachers are called to sit in front of the students as the students repeat a Buddhist chant and sing a song that demonstrates their appreciation for the teachers. The students thank the teachers for having taught well in the past and encouraging their good luck in the future. A few non-Buddhist students sat in the back row and only participated in the presentation of flowers at the end.
