Mr. Chan moved into a new house in UK from China. One day, he visited his neighbor. He found a little girl with golden hair was so pretty. He immediately showed his appreciation by touching her hair. He gave her a gift. She said thanks to him. He told her that she was pretty and polite. After she took the gift and returned to her room, her parent asked him to apologize for his inappropriate appreciation.
Mr. Chan was astonished and his neighbor explained that beauty is not made by her effort. It does not worth any appreciation. Appreciation of beauty would make she think that beauty is her capital. Touching her hair without permit would give her illusion that everyone can do this to her. These actions are not appropriate to her.
On the other hand, she was polite because of her own effort. Her politeness worth appreciation.
Every appreciation and admonishment is the seed in the children's mind, coming along with children's life.
