Everyone in America is extremely concerned with hydration. Go more than five minutes without drinking, and you'll surely be discovered behind a potted plant, dried out like some escaped hermit crab. When I was young no one would think to bring a bottle of water into a classroom. I don't think they even sold bottled water. We survived shopping trips without it, and funerals. Now, though, you see people with those barrels that Saint Bernards carry around their necks in cartoons, lugging them into the mall and the movie theater, then hogging the fountains in order to refill them. Is that really necessary?
