One cries because one is sad. For example, I cry because others are stupid, and that makes me sad.
Dr. Sheldon Cooper, The Big Bang Theory
The saddest thing was actually getting fed up with one another. It’s like growing up in a family. When you get to a certain age, you want to go off and get your own girl and your own car, split up a bit.
George Harrison
I miss the comfort in being sad.
Kurt Cobain, Nirvana
