Me: Have you practiced piano today?
Son2: I just finished.
Me: But you only did your exercises. You need to practice your songs, too.
Son2: I can’t find my piano notebook. It’s been missing for a while. Without my notebook, I don’t know which songs I’m supposed to practice.
Me: Okay. Go look for your notebook.
(Ten minutes pass)
Me: You still need to practice your songs.
Son2: I still can’t find my notebook.
Me (getting annoyed): Okay, new rule. If you can’t find your notebook, then you will have to practice every single song in all of your piano books.
Son2 (20 seconds later): Found my notebook, Dad!
