I like to hear the coffee grinder whir as the galloping beans disappear into a cup of chocolate sawdust.
My clothes iron makes a sound like a whistle when it's hot. The steam is singing.
The shower faucet, as it spins, eeks and gawks, like a ghoul in the wall tapping drunk morse code.
When I was little, the bathtub faucet made a super satisfying KONK with overtones when the water was shut off.
