David and I came to know each other best as young adults, often meeting at Gatwick where he smoothed the way for my parents, his Uncle Bob and Aunt Audrey, as they set off for Singapore and Australia. I have many happy memories of David. One of my favourites is when I arrived at Gleneagles from the US for a business meeting. An intriguing message was waiting for me as I checked in. The message asked me to call a certain room for a surprise. To my delight, David answered. It was a wonderful coincidence that we were there together, and we made the most of it. I will miss David greatly. Tim Sear
