What keeps [friends] together? Common history, some shared conquests, a delight in ideas and people and living. But they will also be distinguished by their ability to listen to you. They will not be uncritical, but they will understand and accept you. You will be interested in each other's happiness and well-being.

Friends with whom you seriously fall out are death. Sometimes it will be completely your fault that this happens, and the shame and sadness of the parting will stay close for a long time.

Bury the shit when you can and fess up if you can't.
