This week I walked with no other purpose but walking. I had not done this in a very long time. I usually have a walk in the morning but it gets justified with a purpose -- the bakery, or the post office, or walking with the youngest daughter to school. The other day I needed nothing, needed to do nothing, apart from walking. At first it felt strange: Where would I go? How would I know? As I walked, ideas came. One street beckoned, another didn't. One direction felt wrong, another right. I even walked down a street that I may have never walked down before, despite having lived in and around this neighbourhood for 15 years. It was a surprise achievement. But ultimately I was happy just to have been walking for the sake of walking. I don't think I can satisfactorily explain how liberating it feels. I think that I have broken through some kind of barrier, one that I didn't even know was there.
