I want to share my last note to Matthew Dear Matthew, I am very sorry to see a note from Bobby to say you are retiring from the University because of ill-health. I have valued your collegiality over the last many years I have had the pleasure to work with you. I very much admired the many ways in which you supported and cared for my PhD students. Your quite tact and diplomacy has guided me through administrative minefields I would have found difficult to navigate without you. I want to thank you for the support you have given me and my students and to wish you peace and contentment. With my best wishes Nick
