"I wanted to become a doctor; I wasn’t able to take up my place at medical school because we did not have enough money for the fees. The closest I’ve ever got to graduating as a doctor is to come and be here with all of you. Congratulations to all of you who have done splendidly well. I gather there are people that got firsts, and people who got upper-seconds - and there might have been people who got something they call ‘Desmonds’... congratulations!"
