To smile at the jest which plants a thorn in another's breast is to become a principal in the mischief.

Colors are the smiles of nature.

I have found that a smile and a stick will carry you through all right, and in ninety-nine cases out of a hundred it is the smile that does the trick.

If the world's a veil of tears, Smile till rainbows span it.

It is impossible to persuade a man who does not disagree, but smiles.
