Why do so many people in life like to watch other people's jokes?

You are too pessimistic. People like that don't deserve your story. It's your fault that you choose to tell people who will laugh at your story. Your friend wouldn't do that. Friends like that are not worth your jokes. You can laugh at them with a harsh sneer. Because they don't know what respect is. You have no reason to reflect on yourself because of them. Keep a clear head and think about what you deserve.
