We were on our way home from Arizona yesterday when from the back seat Caroline spoke up.
"Mom, Dad, I've been thinking about something..."
"Well, I just think people should be reminded not to scratch their butts when they're outside."
"Yes, a lot of people may not know this, but Google Maps might be taking pictures from their satellites at just that moment."
And then she added thoughtfully, "No one wants to be immortalized as a butt-scratcher."
