Can you hear better with the light on, and other silly questions?

Question about non-rational responses to the everyday situations in our lives.

I opened the basement door to hear if the dehumidifier was still running.
At first, I couldn’t tell, definitively, if the bugger was running or not. So, I turned the light on.
I didn’t move to take a step, I just turned the light on.
Yup!
That did it.
The dehumidifier is still running.

Ask a silly question, get a silly answer.
Bonus points if you can ground the question in real life.

See, “Kids say the darnest things.”
