The mystery is solved. It was Andy Roberts that dunnit. As he wrote, I should have given the parcel a detailed look, and I would have realised that it included letters addressed to him.
In my defence, I am feeling rather icky at the moment, and have every intention of going back to bed once I have finished the bloggo. I always get ill after the WW; it is probably my bipolarity crashing and burning, and this year I thought that I had managed to escape, but apparently not.
Whilst on the subject of nice post, I would like to thank Karen Gensheimer for her kind donation. It is only the kindness of you guys, who are so generous with both your time and your money, that keeps this circus on the road. Thank you from the bottom of my heart.
