"Write down or draw all the things that are missing in your life", a woman half Esther Rantzen half an old teacher instructs me. She carries a pile of A2 drawing pads into the room. I thank her singing in an operatic style. She chants back that one of the main things missing in her life is time spent with her husband Desmond Morris(sic). "Perhaps I should add that to my list," I sing in reply.
