The storage rack shifted.

I threw myself toward Leo and shoved him down toward the aisle, out from under it, and I was not quite fast enough, and a heavy supply crate came down and caught his lower leg and pinned it against the base of the seat.

He was hurt.

I could see that he was hurt.

But I could not free him alone, and so I did the only thing I could do, which was to get down close to his face and hold his eyes with mine and keep him looking at me, only at me, while all around us the teachers and the other parents moved the rest of the children toward the exit and worked to lift the weight off my son.

Leo did not scream.
