About a year ago, while walking around London, I saw snails massing on the tarmac path in the rain. A short time later, I saw a shrew on the pavement by my feet. The little shrew then left the pavement to walk across the road only to be clipped by a passing car.
I wondered if it was my fault. Had the shrew fled from me? Then again I didn’t build the road, I didn’t build the car. I had just walked and encountered the shrew.
