My hobbling has made me aware, in a new way, of my vulnerability. When I walk down the street, I notice that very few people actually seem to notice my constraint. And this makes me feel even more vulnerable. I’ve been afraid to take the subway, afraid to be in crowds, uncomfortable even when I am alone at home. I worry about another break, a fall, a misstep—banging into something, or having something drop on my foot.

And I think, with deeper compassion, about my friends and acquaintances—and all the people I don’t know—who bravely endure even greater, often invisible, challenges.
