You ask me for my thoughts on the Cuban question. I regret they are at present unformed as I have spent the past month wrestling with the seating plan for the All Souls Dinner. Freddie will not be happy unless he is at high table. I know I ought to be able to find a way of making this happen, but sometimes the Kantian “ought implies can” is fallible. I have also not had time to commit my apercus on the construction of the Berlin Wall to print; it is, of course, a great honour to have such a landmark named in recognition of one’s achievements, but I am not sure I have done quite enough yet to be worthy of such a legacy.
