Sellotape Trick

Ear phones sellotaped over her ears to stop them falling off (only a bottle of wine could have inspired such genius).

She's listening to Abba. Super Trouper. The rest of us to Leonard Cohen. Hallelujah.

Eldest daughter. "Is this Hallelujah?"
"Yes, the original".
Youngest, shouting. "It's not Hallelujah, it's Super Trouper".
"No we're listening to Hallelujah", I say.
Shouting even louder, "IT'S SUPER TROUPER"

This could easily have gone on either until the next track came on or her ear phones fell off again. Deadlock. The notion that we all weren't listening to Super Trouper just eluding her.

It's quite complex.
