Our neighbor leaves his outdoor lights on all night long.
This morning we all woke up before sunrise so Elizabeth noticed that the lights were still on next door.
She asked me why they had them on all night.
"Probably to keep like possums out of their yard," I said.
"Oh yeah! Because they are nocturnal!" she said.
Seeing the chance for a joke...
"That means that when they come over to your house they KNOCK on the door, right?" I said.
"Uh, no mom. That means they sleeeeeep during the day and stay up all night." she said. "Bats do it, and raccoons and owls and lots of animals."
Dang, she is smart.
