I'm feeling a bit down today, and thought I'd share a quote or three:

Every man has his secret sorrows which the world knows not; and often times we call a man cold when he is only sad.

Henry Wadsworth Longfellow

Sadness is always the legacy of the past; regrets are pains of the memory.

Unknown

One cannot be deeply responsive to the world without being saddened very often.

Erich Fromm

Sadness is but a wall between two gardens.

Kahlil Gibran

Sorrow is like a precious treasure, shown only to friends.

African Proverb

Sorrows cannot all be explained away in a life truly lived, grief and loss accumulate like possessions.

Stefan Kanfer

Misfortune, no less than happiness, inspires us to dream.

Honoré de Balzac

Comedy is an escape, not from truth but from despair; a narrow escape into faith.

Christopher Fry

And finally...a light-hearted one:

Onions make me sad, a lot of people don't realize that. When I'm cutting onions, I'm sad. Because the plight of onions, it's sad. But people don't realize I'm actually crying - they think I'm just reacting.

Mitch Hedberg
