Waiting For You, Right Here On Earth

Tata: I forgot to tell you a thing. It is of vital importance.
Siobhan: What could it be?
Tata: Okay okay okay, so there was Italian Christmas Eve and Italian Christmas Eve 2: Electric Boogaloo. Or New Year's Eve, as the other humans called it.
Siobhan: Yep.
Tata: So Christmas Eve, I kept hearing people burst into fake operatic warbling followed by short bursts of laughter and I couldn't figure out why but it's no big deal because unlike most people in real life, I'm seldom startled when a song and dance number breaks out.
Siobhan: It's one of your more endearing traits, certainly.
Tata: Thank you. I think. Anyway, New Year's Eve, there's that warbling and laughing thing again. So I said, "What are you crazy people talking about?" Auntie InExcelsisDeo said, "Tony and Diana were having a fight and she said, 'Shut up!' He said, 'I don't like your tone' so she sang, 'Shut UP!'"
Siobhan: Oh good. An in-joke.
Tata: ...which won't be funny until you arpeggio your last boss. That bastard is still in your office, right?
Siobhan: I have a meeting in five and my document is ...just...about...done! I'm sick of this project, and I feel an aria coming on.
