Today, we had a little repair work done on the driveway. A couple of the concrete slabs had settled unevenly, so instead of getting a new driveway, we called the driveway jackers. They drill a hole through the slab and inject concrete, "floating" the slab until it is level.
Anyway, my son saw the workers drilling with their jackhammers.
"Hey," he said. "What are they doing?"
"Fixing the driveway."
He looked at me kind of funny, because it didn't seem that they were fixing the driveway at all. I explained the process. Satisfied, he went off to do whatever he does.
Later, after the workers had left, I found my little guy on the driveway with his toy jack hammer.
"Dude," I said. "What are you doing?"
"They missed a spot."
