In times of trouble, you know your friends

A friends eye is the best mirror

The only time you need a friend is in court or in battle

You cannot shake hands with a closed fist (Golda Meir)

Nothing in the world is friendlier than a wet dog

On the road between friends, grass will not grow

The best way to test a man's friendship is to ask him to co-sign
on your note. If he refuses, he is your friend

It's smart to pick your friends - but not in pieces
