Personally, I wouldn't consider any of us particularly reliable. Since Kevin was a boy, and since he was born five years before I was, we had few common interests. That meant we didn't consider each other competition, and that, for the most part, kept us from finding it useful or especially gratifying to persecute each other. The only time he was put in charge of me was when I was in first grade and my parents told him he had to walk me to and from school. This he did without trying to lose me. No running and cutting through people's backyards and climbing fences, which some of my friends' brothers (and sisters) did. I submit that as Exhibit A in the case against Kevin becoming a malevolent ghost. (Though I'd be the first to admit that death changes everything.) When I was in second grade, the people three houses down got a dog that would come to the very edge of their yard and growl whenever I passed. Though Kevin was no longer officially in charge of me, he put himself between me and that dog, and he growled back.
