Instead of loving your enemies - treat your friends a little better.

Don't abuse your friends and expect them to consider it criticism.

There are three great friends: an old wife, an old dog, and ready money.

It may be a cold, clammy thing to say, but those that treat friendship the same as any other selfishness seem to get the most out of it.

The little trouble in the world that is not due to love is due to friendship.

The sounder your argument, the more satisfaction you get out of it.
