I don’t remember the exact day I first met most of my friends, but with Warren Buffett I do. It was 25 years ago today: July 5, 1991. I think the date stands out in my mind so clearly because it marked the beginning of a new and unexpected friendship for Melinda and me one that has changed our lives for the better in every imaginable way. Warren has helped us do two things that are impossible to overdo in one lifetime: learn more and laugh more. Over the last quarter-century of our friendship, we’ve done a lot of both. Melinda and I often find ourselves recounting some gem of wisdom Warren shared with us, or, chuckling when we recall something funny he said or did. To mark the anniversary of our friendship, I thought I would share some of my favorite memories of our time together.
