When I was really small, I used to dream that I could step into the little red tool shed on our back porch, press a button, and a propeller on top of it would lift me into the sky. I used to dream that I would take my sisters for rides in it. I was so young that I didn’t know I was dreaming, so one day I went out to the shed, looking for the button to make it fly. I couldn’t find it anywhere. I thought about this for days. I finally realized the buttons I had been thinking of were the ones that started and stopped the exhaust fan, located upstairs, which sounded a lot like a propeller when it was on.
