A drop of joy.
When I was working yesterday I happened to look up and see a blue tit tugging for all its worth at what looked to be a worm from where I was standing. This rather puzzled me as I didn't think I'd seen this behaviour before. Looking again I could see that what it was actually doing was tugging away at a particularly stubborn thread of moss in the lawn. Intrigued I watched it for a moment as it quickly gathered a beakful of downy material and flew away. I carried on and within a minute or so it was back again, repeating the same process. This time I stopped to track where it was going and to my delight saw it fly into my client's nestbox that she has on the back wall by her kitchen window.
As my client came through I commented in passing about enjoying watching the little bird and how hard it was working. She was so excited as she hadn't known and said how much she will enjoy being able to watch their antics. She is 92 years young with an incredible zest for life. I hope that I have her same joy if I ever reach that age!
