“Hey, F-bomb, you left your Discman on,” says Trudy, and reaches for it.

“Don’t,” says Fern. “I’m starving the batteries.”

“Ah ha. That’ll teach them!”

“Yeah.” Fern grins. “No. I like vinyl better than plastic because it sounds warm instead of sharp. I can’t carry a turntable around, so I work the batteries until the headphones get all fuzzy.”

“That’s not warmth, goofball.” Trudy taps the Discman’s cover. “That’s noise. You can’t tell the difference?”

“There isn’t a difference.” says Fern. “Ask a physicist. Warmth is noise.”

“Then why not just wear crappy headphones?”

“I do,” she says, “I do.”
