Write an upbeat, energetic duet song called "Eternal Argument". Two lovers argue with explosive emotion — loud, fast, playful, then suddenly tender, then loud again. Tempo: driving, danceable, foot-stomping. Music: acoustic guitar stomp, whistling melody in the chorus, deep boom (kick drum or stomp) on beats 1 and 3. Small warm flute solo in the bridge. Male and female voices interrupt, shout, whisper, laugh. Lyrics: family chaos, money vs light, cold vs warm, tea, slippers, sofa, olive salad. Chorus repeats "eternal argument". Ending: "Put the kettle on and make me coffee with love." Overlapping speech, call-and-response, one unison line — tired but smiling, breathless.
