For the benefit of my six-and-a-half-year-old, who was curious about where he lived, my friend Paul sketched a napkin map of London.
The curvy line is the Thames. That's Big Ben and the Houses of Parliament to the left of the first curve. BP, above and behind, is Buckingham Palace. Note the flags, which tell Londoners whether or not the Queen is home. RP = Regent's Park. The three-legged square between Regents Park and Buckingham Palace is Paul's townhouse in Marleybone. (Posh!)
The arrival of Japanese food terminated this exercise in geography.
