What is commonly called Friendship even is only a little more honor among rogues.

—Henry D. Thoreau

The friendships of the world are oft
Confederacies in vice, or leagues of pleasure;
Ours has severest virtue for its basis,
And such a friendship ends not but with life.
—Addison

There are jilts in friendship as well as in love, and by the behavior of some men in both, one would almost imagine that they industriously sought to gain the affections of others with a view only of making the parties miserable.

—Henry Fielding

Friendship is evanescent in every man’s experience, and remembered like heat lightning in past summers.

—Henry D. Thoreau

Give, and you may keep your friend if you lose your money; lend, and the chances are that you lose your friend if ever you get back your money.

—Bulwer-Lytton

I would that I were worthy to be any man’s Friend.
