Paul, my nephew, turned 18 today. My sister asked him: 'what do you want for your birthday?' - 'To go to Barcelona, and see the Sagrada Família', he said. 'Granted', she said. What she didn't know was that he was planning to take both, her and me along. Very nice gesture on his part, I must say, but I must also say that I wondered: what makes an 18 year-old want to hang out with his mother and his aunt in a big city on his big day? I think I have an idea, but I won't disclose it. Not today. Paul, happy birthday, my dear. And thanks.
