I have always laid it down as a maxim -and found it justified by experience -that a man and a woman make far better friendships than can exist between two of the same sex -but then with the condition that they never have made or are to make love to each other.
A woman's friendship borders more closely on love than man's. Men affect each other in the reflection of noble or friendly acts; whilst women ask fewer proofs and more signs and expressions of attachment.
The service a man renders his friend is trivial and selfish, compared with the service he knows his friend stood in readiness to yield him, alike before he had begun to serve his friend, and now also. Compared with that good-will I bear my friend, the benefit it is in my power to render him seems small.
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.
"I can see nothing," said I, handing it back to my friend. "On the contrary, Watson, you can see everything. You fail, however, to reason from what you see. You are too timid in drawing your inferences."
O no, thy love though much, is not so great, It is my love that keeps mine eye awake, Mine own true love that doth my rest defeat, To play the watchman ever for thy sake. For thee watch I, whilst thou dost wake elsewhere, From me far off, with others all too near.
