Laughter and crying can be said to be the most essential exposure of human nature, which truly reflects a person's inner emotional explosion. What can make a person's emotions erupt instantly, and when is it joy, happiness and pain? I recall many past experiences in distress situation. I had fun with my children when I was a child. I met a joke. Usually, when other children made some low-level mistakes or did some silly funny actions or things, a group of children would laugh heartily, even when they mentioned it later. At school, I played cards with my classmates, and some unexpected scenes appeared in the middle. Some people also made some silly mistakes, which caused laughter. Some people were surprised to win the game and were very happy. After work, I like to talk freely with my colleagues about interesting things in life and work, talk about everything on the wine table, and also like to talk about interesting things around me, which makes everyone overjoyed.

Besides, crying, losing something you love, losing someone close to you, and making some irreparable mistakes will be extremely painful when you are helpless, leading to crying. I remember my grandmother was 90 years old when she left last year. During that time, her health was extremely poor. We already feel that time is running out. But when I just heard the news, I suddenly felt that my relatives had left us forever. This life has passed, and she never knows what will happen later. Suddenly, she couldn't help crying. Especially when she is alone, she is more relaxed, and the thought of these painful things can't help but burst into feelings. All these emotions broke out at that moment, regardless of any other external factors, and wholeheartedly focused on what was extremely happy or sad at that time, especially when relaxed and unprepared. Let's think about it.
