Warren and I may seem like a mismatch. I’m a technology nerd. He’s an investor who doesn’t use email. In 1991, when my mother called me to come out to our vacation home on Hood Canal to meet Warren, I wasn’t very interested in meeting him. Eventually, my mother convinced me to come. I agreed to stay for two hours. But then I met Warren. He asked me these amazingly good questions about the software business nobody had asked me before. Two hours passed. And then hours and hours more. It was a deep friendship from our very first conversation.
