Face your books
When your parents or teacher try to be cool by saying ‘face your books’ instead of ‘study’ or ‘do your homework’ because they think it’s a fancy way to say something hip.
My teacher said, 'Face your books, or I'll fail you.'
My mom told me to face my books before I went out with my friends.
My dad said, 'Face your books, or you'll never get into college.'
