Disrupted mouse house

I woke up to an unexpected snowy sky, and though there were forecasts of a three-plus-inch accumulation, I doubt we had as much as an inch of dry powder. Also unexpected was the arrival of a tree-cutting crew commissioned by our local utility company. I had been under the impression that they were going to come last spring to deal with a tree that had rotted in the center and then split down one side. Were it to fall suddenly, it certainly would have taken the wires down with it, but after the company's initial assessment of the danger it posed, no one ever came to remove it... until around lunchtime today. Two highly professional arborists made short work of the oak, then left me to haul logs to next year's wood pile. Praise be... I'm getting ahead of the game for a change. One section was a bit too big to move, so I split it in half with my maul. But when I did, out popped a very perplexed mouse from a nest in what had been a secure hollow in the center. I try to keep my environmental footprint as light as possible, so I scooped up the leaves and grass bits that had been the nest, put them back into the hollow, and pieced the log back together again. The mouse, none the worse for the trauma, quickly returned home.
