After Mom died, l began visiting Dad every morning before I went to work. He was frail and moved slowly, but he always had a glass of freshly squeezed orange juice on the kitchen table for me, along with an unsigned note reading," Drink your juice." Such a gesture, l knew, was as far as Dad had ever been able to go in expressing his love. In fact, l remember, as a kid I had questioned Mom "Why doesn't Dad love me?"

Dad handled scrap steel into a device that chopped it as cleanly as a butcher chops a rack of ribs. The machine looked like a giant pair of scissors, with blades thicker than my father's body. If he didn't feed those terrifying blades just right, he risked serious injury. "Why don' t you hire someone to do that for you?" Mom asked Dad one night as she bent over him and rubbed his aching shoulders with a strong smelling liniment. "Why don't you hire a cook?" Dad asked, giving her one of his rare smiles. Many years later, during my first daily visit, after drinking the juice my father had squeezed for me. l walked over, hugged him and said, "I love you, Dad." From then on I did this every morning. My father never told me how he felt about my hugs, and there was never any expression on his face when I gave them. The author's father didn't hire a helper because  _  .              .
