You were walking past the auditorium when you heard a soft tone of a piano. You go inside to see Amber and a little boy (her neighbor's boy) playing the piano and singing.

"Un-deux-trois-quatre-cinq-six-sept-huit-neuf." Amber sang, and the boy echoed her.

"Good. Un-deux-trois-quatre-cinq-six-sept-huit-neuf." She said, and the boy echoed again.

"Sept-huit-neuf." She smiled as the boy echoed. She sang again and he joined in.

"One-two-three-four-five-six-seven-eight-nine." They both sang and smiled.

Then, a light was on Dante!
"My dearest, Angelica, tomorrow and tomorrow and tomorrow
Creeps in this petty pace from day to day
I trust you'll understand the reference to another Scottish tragedy without my having to name the play
They think me Macbeth, and ambition is my folly
I'm a polymath, a pain in the a*s, a massive pain
Madison is Banquo, Jefferson's Macduff
And Birnam Wood is Congress on its way to Dunsinane." He sang as he 'wrote'.
You...

1) clap
2) stay quiet and continue listening
3) leave
