Stay, my lord, And let your reason with your choler question What 'tis you go about: to climb steep hills Requires slow pace at first: anger is like A full-hot horse, who being allow'd his way, Self-mettle tires him. Not a man in England Can advise me like you: be to yourself As you would to your friend.
If friends disappoint you over and over, that's in large part your own fault. Once someone has shown a tendency to be self-centered, you need to recognize that and take care of yourself; people aren't going to change simply because you want them to.
I don't think life offers any greater experience than the joyful sense of recognition when one finds in a new acquaintance a real friend, or when an old relationship deepens into friendship, or when one finds an old friendship intact despite the passage of years and many absences.
Sometimes in our relationship to another human being the proper balance of friendship is restored when we put a few grains of impropriety onto our own side of the scale.
When I was young I thought of friendship as a matter of total loyalty and unchanging preference and I was often disappointed. But as an adult I had come to see that it was more the refraction of some total faithfulness and joy of which we all had some primordial notion. The exchange of trust and the experience of understanding between two people was like a sign or witness to the possibilitity of eternal caring and understanding and communication.
