Meemaw had come over to babysit while Mary and George attended a church potluck. Sheldon dragged her into his room.

Meemaw squinted. “Sheldon, honey, I can’t hear a thing wrong with it.”

Sheldon Cooper sat in his room, frowning at his laptop. He had just downloaded what he thought was a rare, pristine recording of Eine kleine Nachtmusik conducted by a little-known Austrian maestro from 1958. The file was labeled “FLAC — Lossless — 24bit/192kHz.”

Here’s a short, useful story inspired by Young Sheldon S03E19 (“A Live Chicken, a Fried Chicken and Holy Matrimony”) — but reimagined with a twist about and a lesson in patience, precision, and paying attention to details. Title: The Lossless Lesson
