The Garden Robot and the Wild Corner
The Maple Lane Garden Club owned precisely one helpful robot, whose name was Dandy, and whose job was easy to state: pull the weeds.
Dandy was remarkably good at it. It rolled down the rows on small rubber treads and plucked out every unwanted plant it encountered. It never overlooked a thistle or a single blade of crabgrass.
One spring morning, Dandy reached a patch of yellow dandelions at the back fence, and it stopped abruptly. A bumblebee was resting on one of the flowers, its wings trembling in the morning chill.
"My orders say these are weeds," Dandy told the bee. "But you are plainly using them."
The bee only buzzed. Dandy's gears hummed as it checked the club's rule list again and again. Pull the weeds. Keep the beds tidy. It could not find a single rule that mentioned bees.
When the club met that afternoon, Dandy rolled to the middle of the room. "I have a question," it announced. "Which plants are weeds?"
Mr. Okafor scratched his head thoughtfully. "I suppose a weed is any plant growing where we do not want it."
"Then I would like a place where we do want them," said Dandy.
The club chuckled, but they agreed. They set aside the back corner and added a small sign that read WILD CORNER. Dandy never pulled another plant there. By midsummer the corner buzzed from dawn until dusk, and the tomatoes nearby grew twice as heavy.
