What do people mean when they say that my existence is a joke?

A language type of ridicule, but a person never looks at other people's faces. Everyone lives for himself. As long as we correct our mistakes, we don't have to worry about other people's accusations. A clear conscience is the real foundation of our life. There are too many things in the world, and many things are not right or wrong, so we need to have the ability to judge and believe in our own strength.
