For a number of years now I’ve watched the coming in and the going out of the tide on the Medway river. It never ceases to fascinate. It seems to me that the river is most at rest when the tide is out. I think it’s a bit like breathing – exhaling is always easier than inhaling, emptying easier than filling; and then there’s that brief in-between moment of sheer rest before the next inhalation. Today, as on many days, I saw this brief moment of rest and felt that in the tidal nature of my own breath the Medway and I breathe as one.
