I think we can all agree that cell phones are a blight upon society. People on cell phones can cause you all kinds of inconvenience, being as how they're only paying about 10% attention to the real world. And the crowning touch, the final piece that wins this phenomenon a place in the Obnoxious Behavior Hall of Fame, is that people on cell phones believe they must talk REALLY LOUDLY. Remember when there were phone booths with doors that closed, because we all believed that private conversations were private? How did that get turned around? I don't remember voting on it or nothing. And now I have a tiny part of my brain devoted to the knowledge that little Jake is a monster. I don't have that much intellectual real estate available. I need what I've got to try to understand string theory.
