When the only bond between close friends is attachment, then even a minor issue may cause one's projections to change. As soon as our projections change, the attachment disappears, because that attachment was based solely on projection and expectation. It is possible to have compassion without attachment, and similarly, to have anger without hatred.
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.
First and foremost, be faithful to your superiors, keep all promises, refuse the friendship of all who are not like you; and if you have made a mistake, do not be afraid of admitting the fact and amending your ways.
