If I'm at home for the weekend - and that is almost never - I tend to get twitchy at about eight o'clock in the evening because my body clock is timed to go on stage. I don't know what to do with myself.
Experiments were not attempted at that time, we did not believe in the usefulness of the concept anyway, and I finished my thesis in 1962 with a feeling like an artist balancing on a high rope without any interested spectators.
I'm not possessive, I'm caring... Once you realize a person doesn't want that much care, you automatically back off.
