**Prompt (backup, spoken-word interlude):** Mother and child voices, spoken word, intimate. 70 BPM, key of A minor. Sound: low airplane cabin hum, soft click of opening juice box. Piano: sparse A minor chords, pedal sustain. Cello enters subtly when tension rises (child asks about strange man). Vocals: mother – warm, trembling, then protective (sharp on "No. He's just an old acquaintance"); child – sleepy, then scared and direct. Dynamics: quiet throughout, music stays subliminal. Cello swells slightly then fades. End: mother whispers "Sleep, my dear. The truth can wait a few more years." Single decaying piano chord to silence. Emotion: fragile, protective, ominous undercurrent. Total length ~1:30.
