I think the answer is: not at all.
Great night watching musical Juliet and Me at the Finborough: there was tap dancing and an actor inadvertently launched a maraca at me during a very strange "south of the border" sequence. But the highlight was really the nice visit I had with the guy I went to the show with; we have far more in common than I thought. He may be my post-theta_g lodger: the need for one is clearly not going away.
Tomorrow is book club and a movie at the Barbican; I need to get 40 pages more read of Lady Chatterley's Lover before then. I don't think it will be too hard; it's actually a very good book, and very thoughtful. What I want to do is have pancakes for breakfast with someone and go for a walk in Richmond Park as it's supposed to be sunny, but that kind of stuff is all part of my old life and learning to live without it is part of my new one.
