"I do not call you servants any longer... but I have called you friends..."
This is one of my favorite quotations on friendship:
And here's the other:
When a friend is in trouble, don't annoy him by asking if there is anything you can do. Think up something appropriate and do it.
A real friend is one who walks in when the rest of the world walks out.I don't know who said that but it's very true. And real friends are very rare.
