Turning toward our house on the hillside, I see movements of a different kind, tall shadows stiffly pushing through the currents.
I think it refers to her brothers, mother and father. But I'm not sure. Could you explain it to me please?
The fuller text is here:
The hill is paved with wild wheat. If the conifers and sagebrush are soloists, the wheat field is a corps de ballet, each stem following all the rest in bursts of movement, a million ballerinas bending, one after the other, as great gales dent their golden heads. The shape of that dent lasts only a moment, and is as close as anyone gets to seeing wind. Turning toward our house on the hillside, I see movements of a different kind, tall shadows stiffly pushing through the currents. My brothers are awake, testing the weather. I imagine my mother at the stove, hovering over bran pancakes. I picture my father hunched by the back door, lacing his steel-toed boots and threading his callused hands into welding gloves. On the highway below, the school bus rolls past without stopping.
