There's a guy who runs at the river who's blind. He runs with a partner. They loop their wrists together with a thin rope that leaves maybe 12 inches between them. The only way I know which one is blind is that the partner occasionally changes. Every time I pass him, I immediately close my eyes and try to run a few steps without seeing. I can't imagine what it would be like--the trust, the dedication, the persistence.
I close my eyes when I brush my teeth. Is that common or is that strange? I don't know.
