Here’s the setting: You’re sitting in a restaurant with your friends enjoying dinner. This is one of those restaurants that offers complimentary ice cream cones after every meal, and the ice cream machine has been getting a steady stream of traffic since you sat down. As you watch, kids all across the building scarf down their food with enthusiasm before turning (with mouths still full of their last bites) to their parents to get permission to go get ice cream. The kids can hardly stay in their chairs, hopping down and running to the ice cream machine as soon as they get the go ahead. You watch as little boys and girls figure out just how high they can get their soft serve to go on their little cones, and you laugh as the once clean faces are now being painted with vanilla. But then you notice one little boy crying.
