After a rough lesson on the Third Commandment---where my students were in open rebellion about the requirement to got to Mass every Sunday and one kid defiantly said, "I'm not even going to Mass on Christmas!", I started a game of "telephone" to lighten the mood.
I'm so glad one of the first messages to pass along in a whisper was "Going to Mass stinks!" Clearly, my lesson on the importance of "Honoring the Sabbath" made a wonderful impression! :-)
