What kind of mentality is the person watching the joke?

People who like to watch other people's jokes have a latent psychology. They will be happy, comfortable and satisfied as long as they see that others are not doing well. A mentally healthy person, the premise is carefree life, emotional satisfaction, positive spirit, the whole person exudes a positive energy aura that can attract others every day. As long as these conditions are lacking, or people who lack these conditions for a long time, this extreme psychology will occur over time.
