Not quite tall enough

This morning we took a walk in the park with Jacen. As we walked Jacen kept pointing to the sky and saying, "cloudy". He had picked up a stick and ways doing the boy thing with it-- dragging it on the ground and poking and hitting things with it. Pretty soon he stopped and pointed the stick in the air as far as he could reach. I asked what he was doing and he said, "Reach it. Clouds." I told him the clouds were too high up for him to touch, but the rest of the walk whenever he stopped he stretched his stick up to the sky again, trying to touch birds, airplanes, or whatever else he could see up there.
