I wrote something several months ago about Peter Rabar, an agency legend I had the privilege to work for, and to learn from. It was called "In Peter We Trust." The piece, on one level, talked about the nature of the client-agency relationship -- that is, what it takes to achieve a long-term, productive one. And it questioned whether we were talking ourselves out of the notion that such a quaint concept can apply today, with so much more specialization, technology and pace. There was another lesson Peter taught me, which happened on a very busy winter day.
