If one day we meet again on the road, and I tell you, "I'm very happy now." I must have pretended to be happy if I can only meet you again instead of living together? I told you that I was happy, but I didn't want you to know that I was actually very sad.
If you give him a dollar every day and you don't give it for a day, he will hate you. If you give him a slap every day and don't slap him for a day, he will kneel down and thank you. Human nature is like this, life is like this, and love is like this.
Slowly, you will realize that there are really few things in life that are worthy of our courtesy, education, character and structure.
