To Father, peeling potatoes is not a chore, but precision work. When he reads, he has a deep wrinkle in the back of his head. But when he’s preparing potatoes, beans or vegetables, he seems to be totally absorbed in his task. He puts on his potato-peeling face, and when it’s set in that particular way, it would be impossible for him to turn out anything less than a perictly peeled potato.
