"Why do I always have to do all the dirty work?" asked the boy as he picked up his dropped toy. It caught the attention of a passer-by, who laughed. "That sounded like something he learned from a show," she said to the boy's father. She leaned down to the boy. "I'm sure it might seem like you do all the dirty work, but there's a lot that adults do that you don't even think about." She straightened and stretched her back. "Isn't that right?"

"No," said the father. "He does all the dirty work. See," he said to the surprised woman, "I'm something of a complete and utter germaphobe, and he does all the work that brings one remotely close to dirt, filth, or soilment of any kind."

After an effort to shut her mouth, she said, "What about his mother? What about your mother?"

"Also a germaphobe," said the man. The boy nodded.

"So you..." she started.

"Sweep, mop, vacuum, scrub the toilets, do the dishes, clean the fridge, and wipe my parents after they use the toilet."

"But... what do you do while he's at school?"

"Oh," the man smiled, "don't worry about us. We home school."
