# C08 · Music and a puzzle · ordinary Day 14

**Complete source:** C08 fictional room notes: one user wants rehearsal, another quiet puzzle; no booking system, sound test or agreement.

<summary>Ordinary educator example — after an own attempt</summary>

**Worked reasoning after own attempt:** Different times might reduce overlap; need booking/opening information before calling it a real timetable.

**Limit/next check:** Quiet is not a diagnosis; music is not assumed irresponsible. No invented preference survey.
