Dan Waitz vividly remembers the time a few years ago when he gave his oldest son Grant and his other children each a quarter at a restaurant so they could get a piece of candy out of a gumball machine. A few minutes later, I looked over at the kids and everybody was chewing gum except Grant, Waitz recounted. When I asked Grant why he didn t get a gumball, he said he put the quarter in the container on the counter they were using to raise money for kids with leukemia. That s the kind of person Grant was: the most caring, compassionate, kind kid you d ever want to meet.
