Saturday night I watched four kids. There was a little bickering (boys vs. girls!) but mostly we just used sidewalk chalk, ate pie and watched Disney Channel. Oh, and there was one piggyback ride that resulted in a double-decker Velociraptor impression. When bedtime rolled around, they were supremely cooperative.
When I checked on them later I noticed the sign on the boy's bedroom door:
Way better to come across on a kid's door than half a jar of smelly face cream.
