Yesterday I went into town to do a little bit of shopping. I bought shoes. I stopped for a drink on my way home. When I left it was around 5pm and lot’s of people had piled into the street, also heading home it seemed – probably from work. As I walked amongst them, and weaved in-between them trying to avoid a collision, I had the startling realisation that I didn’t have the slightest clue who any of them were.
