On Dogs and Robots

Colin asked me if dogs were friendly. I said that dogs were friendly, but their job is to protect their owner. So, I said, if you had a dog and a bad guy came near you, the dog would bark. (I gave an impressive performance of a barking dog.) And if the bad guy still didn't go away, I said, then the dog would bite him. (Again, I earned an Oscar.)

"So," Colin said, "a dog's job is to..." (he trailed off, as if unsure.)
"Protect its owner," I finished for him.

He smiled wide.

"Just like robots!" he said.
