When I was in college, I knew this woman who played the piano with the best of them. By that I mean she could turn her own pages, sing, and ad-lib. Not so special until you looked at her fingerless hands! She was born without fingers, and the doctors grafted tiny little crooked nubs to her knuckles, and that's what she played with. And she didn't just play well "considering what she had to work with", she played really well! Ever since, I assume that those who ae deficient in one aspect, either physical or mental, has a special message for the world or something to teach us. I'm waiting for someone to come along to teach me how to write without using so many commas.
