Have you noticed how nobody ever looks up? Nobody looks at chimneys, or trees against the sky, or the tops of buildings. Everybody just looks down at the pavement or their shoes. The whole world could pass them by and most people wouldn't notice.

Courtly love-poetry may first have been written during long periods of abstinence on the Crusades, but it would not have flourished in the cold of northern Europe without some help from the chimney.
