I remember the first snowfall with our dog. Not because my memory is exquisite and able to retain every detail of my time with the pup, but because this one thing stood out: I could see what her nose was smelling. The many sudden yanks of the leash I had experienced while walking together (and been at times frustrated with) suddenly made sense. The world that I could not see until then had been revealed by that white cover (it sounds a bit backwards and ironic but it is not at all.)
