Literal Translation

I was at a friends house yesterday. Mster decided to play the piano. She wanted to turn the pages to the music book to get a new song but the book was old and I was worried that it would tear. I said: "Mster, we have to put these books away. You are just going to have to play songs out of your head." To which Mster started banging on the piano with her forehead. Oops.
