Is it because other people’s lives are unhappy, so they like to make others laugh?

This is the fact. This is actually caused by human psychology. Everyone cannot see others living better than themselves, and they do not know how to bless others. They always feel that others are living better than themselves because God is unfair to them. .

So when others are not having a satisfactory life and are unhappy, it becomes a source of conversation and laughter for others after dinner.
