Up until this year, I'd never owned an iPod, and it's been years since I lost my portable CD Player (which didn't get as frequent a use because it was cumbersome). I got an iPhone for Christmas, and now I've got those little white speakers in my ears all the dang time. I take care to look both ways twice before I cross the street, and try to be conscious at all times, but still, I think I am going to get myself killed with these goddamn ear buds. Two days ago I was walking around in the grocery store, grumbling to myself about oblivious people who walk too slow and not paying attention to their surroundings. Not thirty seconds after thinking these highly hypocritical thoughts, I turned around sharply and almost ran into someone. It was totally my fault. New rule: no more ear buds in the grocery store. Did you have to set rules for yourself when it comes to personal audio systems (or whatever they're called)? If so, what are they?
