I have a very old friend who has been wonderful over the years. I think the friendship has become a very entrenched habit. In recent years I have noticed they misinterpret me a lot. They give advice when I’m not asking for it, and misunderstand me and then try to psychoanalyse me. I now feel that I can only talk about an increasingly small number of subjects. I don’t know how much friction is normal in a very very very longstanding friendship.
