“You know how the story goes. You’re sitting in the theater, enjoying the movie, and then suddenly you hear the distinctive sound of a cell phone ringing. You sigh, shake your head, and silently wish ill will upon the perpetrator (seeking the Lord’s forgiveness later, of course). You figure common courtesy will rule the day and the guy will silence the cell phone and all will be well. It takes approximately 2 seconds to realize that you should’ve brought a calculator because you figured wrong.”
