If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

I don't want to be alone, I want to be left alone.

Absolutely lonely people have few personal interactions of any kind.

Every man must do two things alone he must do his own believing and his own dying.

Only the lonely know the way I feel tonight.

As I get older I'm more and more comfortable being alone.

A man content to go to heaven alone will never go to heaven.

The best part about being alone is that you really don't have to answer to anybody. You do what you want.

Living alone makes it harder to find someone to blame.
