We have one light switch that turns on a very small light on the middle landing of the stairs in our house. We never turn it on.
Last night, I walk in and see it on. I can't figure out how/why that happened.
"Tamar, did you turn that light on the steps on?"
"No, Calanit did."
"What? How did that happen?!"
At that moment, Calanit walks in with her hula hoop and proceeds to demonstrate how she can turn light switches on and off using it as a tool.
Necessity is the mother of invention, eh?
