I remember a rather elderly woman once asked me if we had a particular book, and I typed its title to check while she watched me intently. After I told her where to find it, she started to walk away, but then she turned and came back.
“Your typing,” she said. “You typed with all ten fingers.”
“Can you look something else up for me?”
“Anything. I want to watch you type again using all your fingers.”
Is it possible to have self-conscious fingers? Mine suddenly felt very naked.
