We were at the mall today, and Liam had to potty. I brought him, he used the urinal like always, but it was an auto-flush. But it wasn't the regular type of auto-flush, it was like a manual flush that had been upgraded, so where there used to be a flush handle, there was a black box with a sensor. So inside the black box was basically a servo motor that performed the same action as physically pulling the handle. Since it was a motor, it made a "Wzzzz" sound when it flushed.
Obviously, Liam was too short for the sensor to detect his presence, so he had to press the button to flush. When he did, and it made the noise, he said, "What was that noise?" I told him that it was a motor that flushed the potty. "Why it sounds like a parrot?"
