If you have a foreign friend who does not understand any Thai culture. How would you explain your friend to know how important Wai Kru Ceremony?

I would ask him to travel around Bangkok about Thai culture. such as going to temples, eating Thai food, talking to Thai peoples and go on a boat at chao phra ya river. next that I will help him understand every important days in Thailand such as Thailand Father’s day and mother’s days. Later I explained to him about Wai kru ceremony that we  need to thank teachers that teaches us on the years. Then he will not be that confuse because he knows a lot of Thai cultures since he do a lot of things with me that is Thai original.
