So I got an electric toothbrush, which is charmingly efficient. You push a button, it brushes your teeth for exactly two minutes and beeps at intervals that indicate when it’s time to change sectors. My teeth are shiny and new–they do the little lens flare thing when I smile. The only problem is, my new toothbrush sounds very much like a vibrator. My roommate has begun to avoid eye contact with me when I leave the bathroom.
