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.
We poets would die of loneliness but for women, and we choose our men friends that we may have somebody to talk about women with. Letter to Olivia Shakespeare, 1936
I am thankful for small mercies. I compared notes with one of my friends who expect everything of the universe, and is disappointed when anything is less than the best, and I found that I begin at the other extreme, expecting nothing, and am always full of thanks for moderate good. . . . If we will take the good we find, . . . we shall have heaping measures. . . .
Almost every man we meet requires some civility; requires to be humored; - he has some fame, some talent, some whim of religion or philanthropy in his head that is not to be questioned, and which spoils all conversation with him. But a friend is a sane man who exercises not my ingenuity, but me.
. . . For friendship implies individuality; whereas comradeship really implies the temporary subordination, if not the temporary swamping of individuality. Friends are the better for being two; but comrades are the better for being two million.
