There was a moment in Ian McKellen's Lear when the old king, following the example of Poor Mad Tom, says "Off, ye lendings!", and starts stripping off his clothes. The people around him are talking to each other, trying to Not See what's going on as Lear drops his pants and jacket, and then tries to pull his shirt over his head and gets stuck there -- an old man, naked in public, tangled in his shirt. My thought at the time were Gloucester's words, "And that's true, too."
I thought of that scene again last night, watching a naked old man get stuck in his shirt. I tried explaining to him that his oxygen line was in the way. Still, he succeeded. He was determined. Off came the oxygen. When he tried to pick out his feeding tube I grabbed his hands to hold them. When he tried to crush my fingers, I was kind of glad he'd found something else he could focus on. Also that he didn't have much hand strength. When he smacked me (not hard) for standing in the way of his escape, he said words to me he used to smack us for using.
I was not shocked. Poor guy. So much for those old lessons. Everything I ever learned I appear to have learned in the playhouse.
