After Sunday vigil Mass I watched a little boy crawl on the floor. Later he amused himself by running laps around the church. The look on some of the faces of the adults who watched him would've curdled milk. His mother said not a word to him and appeared to be completely at peace with his behavior. She reminded me of a young father who once asked with apparent sincerity, how the people who couldn't stand his noisy kids at Mass would stand being in Purgatory. Where do these people come from?
