Peaches

Peaches that have gone bad make a particular sound when you cut into them. Sometimes only half of the peach is off, so I cut the whole thing, listening for a good bit.

A teacher will consciously notice this sound when instructing someone in the art of peach pie, and will stop to point it out. There, that sound, yes, if it sounds like that it's overripe. See, the texture's spongy. A good peach is smooth and silent and bright gold. It might still cook down all right, if the color's good; but if it's discolored just pitch it.

A writer will consciously notice this sound when writing a scene in which someone is making a peach pie, when summoning up the huge mound of details about the process from which she will select one, or maybe two, that will enable the reader to extrapolate the experience of peach pie making without spending a lot of space on it, that will create the maximum effect from the character's innocent, sunny, summery activity while the villain sneaks up behind her with a garotte.

A poet will consciously notice this when writing a poem about summer as embodied as a peach.

A great poet will make someone who has never sliced a peach hear the sound.

This is all probably analogous of something profound. But for some reason I'm hungry...
