A border terrier reflecting on the meaning of life

We waited all day for the rain to stop, and when it eventually looked like doing so, we drove to Stratford for a walk alongside the river with Hector and Ziggy (our Bedlingtons).
On the way we met this little border terrier (don't worry, dear reader, he was with his man-servant), and he was having a lovely time running round in circles and cornering as only a dog with little legs can corner.
When he was exhausted he stood a while - to reflect.
