Many of us are familiar with this image. If you commute, you’ll have seen it countless times; maybe not this image exactly, it could be a man, or a different coloured paper, or a book or an electronic device. Its that ‘Don’t bother me!’ image. People guarding their personal space on their way to and from work. Life in a modern city anywhere in the world is tough. I often wonder how we do it, how we keep doing it, and whether we’ll know when enough is enough.
