Why are children afraid of being laughed at?

If a four-year-old has stage fright, he is afraid of being laughed at by others. There's nothing to be surprised about. After all, I have never experienced anything when I was a child, and I will definitely encounter stage fright on some occasions. If a child has experienced many things and many occasions since he was a child, it is his turn to speak when he meets some necessary occasions. He won't feel the aura There are more occasions and more people, so he won't feel strange when facing people. And I'm not afraid of jokes, so it's related to the child's experience.
