You're a middle school musician. Your orchestra has just finished rehearsing a rather slapdash rendition of a piece. You could stare sullenly at the music after such a reckless performance, or you could do what I once saw a cellist do.
At the end of the piece, she turned to the other players in her section and announced, "Thank you! I did it all!"
It won't salvage the piece, but at least, everyone will have a good laugh.
