Be true to your work, your word, and your friend.

A true friend is someone who is there for you when he'd rather be anywhere else.

You can always tell a real friend: when you've made a fool of yourself he doesn't feel you've done a permanent job.

Let there be no purpose in friendship save the deepening of the spirit.

A true friend never gets in your way unless you happen to be going down.

To like and dislike the same things, this is what makes a solid friendship.

He has no enemies, but is intensely disliked by his friends.

But friendship is the breathing rose, with sweets in every fold.

Never contract friendship with a man that is not better than thyself.

It is one of the blessings of old friends that you can afford to be stupid with them.
