As a mid-aged man, I was always worried about my weight. Every time when I walked on the street, I would see fear on others' faces as if I were a giant (巨人).

"Walking a dog will help you." suggested Doctor May.

"Walk a dog? I've never had a dog." I said.

"I have a perfect dog for you!" said Doctor May and she showed me a large black-and-white dog with a big round body. He looked up at me and then dropped his head with a clear look of aversion. He didn't seem to like me. Neither did I.

"He is Peety. As no one cares for him, he's too heavy now and needs exercise," said Doctor May. Looking at the poor dog, I saw the terrible life he had had. I touched him carefully. He seemed to like that and lay down near my feet.

The next day, we started our first walk. Although Peety didn't walk very fast, I was tired out. You could clearly hear my footsteps on the road—thump, thump, like the giant from Jack and the Beantalk.

"I can't go on!" I shouted to him, lying on the ground. Peety ran back and looked at me quietly.

"Oh, Peety," I said. "Do you really want a walk with a giant like me?" He kept looking at me with those beautiful dark eyes and waited in silence. I knew I wouldn't make him upset.

Over the next weeks, we kept on walking. There were times when I couldn't catch up with him. He would just look up at me like I was the greatest man in the world—and that's what I wanted to be for him.
