My brief sojourn in London with Luca

En route to Nairobi, I've been able to spend 5 whole days with my sister Rabia, her husband Pascal and their darling 10 month old son, Luca - my nephew. This being my 5th or 6th time to London, I've no desire to see Trafalgar Square or Buckingham Palace. Instead, my time is devoted only to Luca until I depart for Nairobi on Monday. Isn't it obvious why?
