'Every truth has two sides; it is as well to look at both, before we commit ourselves to either.' - Aesop.
There are two sides to London. Its public face, the one that the tourists come here to see, and its private face, the one that the folk who live here experience.
For various reasons, I've ended up sitting on the steps outside the National Portrait Gallery at Trafalgar Square twice this past weekend. It isn't a hardship - I love people watching and it's a really good spot for that particular activity. Most of them are tourists - selfie sticks abound, people haul themselves up onto the base of Nelson's Column for photo opportunities, kids run about squealing between the fountains and crowds gather to watch the street performers who juggle, joke and dance for loose change.
