One afternoon while I was talking to a professor, my two-year-old daughter Melissa wandered into a nearby classroom. A math class was in progress, and to my dismay, Melissa sat down in the front row.
When I went in to get her, the instructor stopped me. "Young lady," he said, "I have been teaching calculus at this college for over 20 years. Not once in that time has anyone come to my class just because he or she wanted to. The child may stay."
