The white stone - again

If you were reading this in September, you'll remember my fascinating post about the weird white stone in my washing machine. I am sure you have been wondering about it ever since, and therefore feel compelled to report that it has gone.

I know I didn't remove it, and as I am the only person who uses the washing machine, I can only assume that (a) it is inside somebody's clean pants or (b) it fell out unnoticed or - worst-case scenario - (c) it is now lodged within the workings of the washing machine and will shortly cause complete and irreparable breakdown of said appliance.
