There are certain 16-year-old girls in my classes who have acquired the habit of making requests using baby voices. In regular conversation they use regular voices, but when they approach me wanting something from me, they switch into a shy, childish voice. It drives me up the wall. My first inclination is to snap at them and refuse the request simply because the voice is so irritating. I have to pause and remind myself that what they're asking is generally pretty reasonable. I could like these girls if they'd lose the self-conscious pretense and the voice that accompanies it.
