I loved this post, like, a lot. Like Zack (I'm assuming the first commenter is Zack), I saw Red last week. They made their "turn off your cell phones" announcement. When it was done, as you would expect, lights flashed on all over the place. One was in the row in front of me. Another guy in the row looked at the person with the cell phone and hissed, "Turn that off!" To which the person answered, "That's what I'm doing!" All over the room, there was shushing, and glaring, and the whole array of schoolmarm discipline all over the place.
This is honestly far more disruptive than any coughing, or even a cellphone ring. There just comes a time when you let it go, folks. Chill out.
