Human happiness is not connected. What is this?

People's happiness is not interrelated. It's an online buzzword, which originated from the lines of a movie "The True Story of Teddy Boy". This sentence means that everyone has his own value and pursuit, and can't force others to have the same happiness as himself. This is also an attitude of mutual respect and understanding. This sentence is widely quoted on the Internet and has become a way for people to express different understanding and respect.
