English Class
I was, until this past weekend, a tourist, and I loved it.
Usually, my wife and I simply strolled through the City of London (and Westminster, etc.) with our hosts. Often, though, they enjoyed some professional sightseeing assistance. These are very informative, and they reveal certain traits about other tourists--usually Americans. For example, after a guide pointed out a monument to the fire that began in a bakery in 1666 and razed London, a fellow yank asked, "Is that shop still around?"
And in a tour that we had nothing to do with, we caught the following snippet from a young tween boy: "...one of the greatest feats of religious architecture: the Harry Potter dome..." I'm sure that, in context, this was just as nerdy as it sounds out of context.
