Diclaimer: Naruto nor the book where I get these from is my copyright
Being a dad means sitting in the labor room in the dark and listening to Pavarotti.
Pavarotti was Sasuke''s suggestion. He had heard that classical music was good during labor. Naruto didn't want it. He found classical music to be boring and often put him to sleep. To prove his point Naruto was fast asleep still hooked up to the machine in his labor room.
Naruto's water hadn't broken completely yet and the doctors decided it would be best if he took a nap first before they moved on. Sasuke and had turned the lights off and played Pavarotti. The baby would enjoy it even if Naruto couldn't.
And for once Sasuke could enjoy Pavarotti in peace.
