I did not know it at the time, but taking a summer job at a camp for underprivileged children was one of the most important decisions of my life. There I met a seven-year-old boy named Tommy. Although it was many years ago (I had just completed my first year in college), I still have a vivid memory of our first encounter. While hurrying to a meeting with the camp director, I heard some boys fighting nearby. I ran over to find Tommy on the ground fighting two larger children. I helped break up the fight and then hurried to my meeting. When I mentioned the incident to the camp director, I was surprised when she nodded knowingly. Although it was only three days since the camp opened, the staff had already surmised that Tommy had a gift for evoking the ire of those around him. I was puzzled by his strange behavior and decided to observe him more closely.
