What moves me, right away, is the gentleness. They're standing a few feet apart, two adults younger than I am, each of them coaching someone elderly. They help them rise from their wheelchairs, stand with relative stability, and toss a bright plastic ball back and forth, back and forth. Each of the patients wears a wide striped belt for the therapist to hold onto.

After the game of catch, they work with cones. Each plastic cone is slightly smaller than a soda can, and each is a different vivid color, red and green and yellow and blue. Each physical therapist holds a cone somewhere just out of reach, and prompts their patient to reach for it, to stretch or bend as needed, and then to hand it to her or his counterpart. Back and forth.

Afterward I chat with the woman I am there to visit. She praises the physical therapists: they're young, she agrees, but they know what they're doing. She tells me that she's gotten to know everyone there, at least enough to greet them and say hello. And when someone is in really bad shape, she says, and they manage something they hadn't been able to do -- that's inspiring.

It has the feel of a kind of strange private club, though not a club anyone particularly wants to join. Its accoutrements are so determinedly cheerful they remind me of preschool. My son would love the mats, the cones, the ball. I wonder how many of the people there wrestle with frustration at needing to practice things like balance, or grasping, or bending down.

What fragile things these bodies can be. Thin skin and delicate bones and so many places that can hurt. I want to bless the hands and heart of every doctor and nurse, every physical therapist, every orderly. Afterwards I take myself out for a quick Chinese lunch. I warm my hands on a teacup. I whisper prayers into my tea.
