Jack used to curse(咒骂) the front yard as if it were a living thing. He was the man who lived with my grandmother for thirty years. He was not my grandfather, but an Italian who came down the road one day, selling fruit in Florida.

Jack stopped at my grandmother’s house to sell her some oranges just a stone’s throw from downtown Miami, and he was delivering her whiskey a week later. He stayed for thirty years. Jack hated the front yard because he thought it was against him. There had been a beautiful lawn(草坪) there when Jack came along, but he let it wander off into nothing. He refused to water it or take care of it in any way.

Now the ground was so hard that it gave his car flat tires(轮胎) in the summer. The yard was always finding a nail to put in one of his tires or the car as always sinking out of sight in the winter when the rains came on. The lawn had belonged to my grandfather, who lived out the end of his life in an insane hospital. It had been his pride and joy and was said to be the place where his powers came.
