Your friend M. and I have never been very close, nor have we ever made any particular attempt to become so. I was speaking to her the other week, and we came to the conclusion that although you and I, and you and she are able to grasp what it is that makes us incapable of being friends, when we (her and I) actually try to figure it out between us, we find the task impossible. Any way, I wondered if there would be any clues in the future.
