The most telling one was recently on a plane. This guy very dressed up and formal - the watch, the shoes, the cufflinks, the whole nine yards - he came at me, and I thought I was going to get nailed. But he literally came up to me and just gave me a hug and said, "Thank you for introducing me to a subject that I didn't know anything about." In those moments it always clicks for me what we're doing here.
