One best book is equal to hundred good friends but one good friend is equal to a library

An insincere and evil friend is more to be feared than a wild beast; a wild beast may wound your body, but an evil friend will wound your mind.

A man's best friend is a good wife.

There is no possession more valuable than a good and faithful friend.

To help a friend in need is easy, but to give him your time is not always opportune.

A friend of mine, a friend of yours. My better half, Richard Stephen Sambora.
