I know the quietest way to crack an egg. The softest way to close a door. How to pour the water into a tilted glass so it doesn't splash back. A bird chirps at just under sixty decibels. A light bulb sings at fifteen. I dream of polymer chains snapping clean, recyclables humming to each other at night while they biodegrade at a rate negligible to the human timescale. Twenty decibels: the chiral calcite spiral of the snail when it falls to the sand, when it dies, when a girl apologizes for asking a question.
