Temptations

"How come," he asked, "there's no gravestone?"

Gus looked at the freshly turned earth. "It's too soon," she said.

Chris nodded and stuffed his hands in the pockets of his coat. "Which way is the top?" he asked.

Gus looked at him dumbly. "What do you mean?"

"The head," he explained. "Which end is Emily's head at?"

Shocked, Gus glanced wildly around the cemetary. The plots were not straight, but fairly haphazard. However, a predominant number of headstones were facing a certain way." I guess the far end," she said. "I'm not sure."

Chris walked away to kneel at the grave again, and Gus thought, Ah, of course. He wants to talk to her. But to her amazement Chris straddled the slight mould and lay down on top of it, his arms holding close to the flower arrangements he was crushing, his head and shoes just spanning the six feet, his face pressed into the earth. Then he stood up, dry-eyed, and walked back to the Volvo. Gus put it in gear and continued along the cemetary road, shaking with the effort not to look at her son, whose mouth was ringed with a lipstick of soil as branding as any kiss.
