Yung-Cheng, Emperor of China in 1727 said:
"The people of the world are bigoted and unenlightened. Invariably, they regard what is like them as right and what is different from them as wrong, resulting in mutual recrimination. They do not realize that the types of humanity are not uniform and that their customs are also not one, that it is not only impossible to force people to become different but also impossible to force them to become alike."
In teaching etiquette classes we always say: It is neither right nor wrong, just different.
Remember these words when travelling on vacation this Summer and enjoy!
