Why doesn't anyone laugh at your jokes?

People don't laugh when you tell jokes because you don't know humor; You incite others not to cry because you are not sincere enough. If you don't understand humor, you can learn humor. If you are not sincere enough, you can become sincere. Everyone's laughter and tears are not cheap unless this person is a fool. If you don't know humor and want to make others laugh, if you are not sincere enough and want to make others cry, your weakness will be exposed to the cold and indifferent eyes of others.
