Grandboy: Why the Christmas lights outside shut off in the daytime?

Me: O that’s because of the photoelectric cells. They see the sun is up and flip the switch to cut off the flow of electricity to the lights.

Grandboy: Oooooh. And when it’s darktime the phonolen thing it turns on the lights.

Me: Yep.

Grandboy: But I can PRETEND they turn on and off with MAGIC, right?

Me: Sure! Nothing wrong with pretending about magic. Boom you’re a monkey.

Grandboy: Now I’m hungry Gwumpa. I can have banana now?
