Love begins with the experience of being understood in highly supportive and uncommon ways. They grasp the lonely parts of us; we don't have to explain why we find a particular joke so funny; we have the same people; we both want to try that rather specialised sexual scenario. It cannot continue. When we run up against the reasonable limits of our lovers' capacities for understanding, we mustn't blame them for dereliction. They were not tragically inept. They couldn't fully fathom who we were - and we could do no better. Which is normal. No one properly gets, or can fully sympathize with, anyone else.
