As a dedicated observer of things happening right outside my house, I can testify that that big puddle has been there for three months

I’ve never needed to be convinced of the cognitive benefits of looking out the window. I would do it all day if I thought people couldn’t see me.

I’m currently staring out of our front window, arms folded, at the large puddle running along the road’s edge outside our house.

It normally appears after a sustained period of rain, and disappears after a day or two. But as a dedicated observer of things happening outside this window, I can testify that the puddle has now been there for three uninterrupted months. It’s a foot deep in the middle and too wide to jump across – more moat than puddle. I’ve come to suspect that rain has nothing to do with it: the puddle is being fed by an underground source.

Today’s events seem to confirm my opinion: as I watch, a man in a hi-vis vest is placing cones around the edge of the puddle.
