Dear Diana, Justine and Jacob. I send my sincere sympathies to you all on the loss of Mark. He was a light in your life. We only met briefly in Australia at the AMQC in 2005, but Mark brought such joy, fun and laughter to all the classes I attended. I'm sure your lives were very much enriched by having him in your life. He made a huge impression on me over a short period of time. He will be sadly missed in this world. All the best to you all in your future. Know that we think of you around the world. Vanessa Dukovic##imported-begin##Vanessa Dukovic##imported-end##
