The carpenter I hired to help me restore an old farmhouse had just finished a rough first day on the job. A flat tire made him lose an hour of work, his electric saw quit, and now his ancient pickup truck refused to start. While I drove him home, he sat in stony silence.

On arriving, he invited me in to meet his family. As we walked toward the front door, he paused briefly at a small tree, touching the tips of the branches with both hands.
