I found the book!
And that wasn't the first find, either. Yesterday I got to sit in my big armchair for the first time in ages, turned to look at the books on the shelf beside me and
A library book I had to report returned or possibly missing back at the beginning of the summer was sitting right there with its spine neatly presented.
I was thrilled, but then annoyed that I hadn't found the mitten book, because I am essentially an ungrateful person.
Also: overly suspicious. I was really starting to think that there might be a prank-loving ghost living in my house because I not only lost that book, and the mitten book, and a bottle of sunscreen that was expensive and hard to source for replacement purposes, but also my compact umbrella (pink with little cars, now out of production and purchased to celebrate having got my learning-to-drive permit.)
Having found the library book on the shelf today, and the mitten book just now - it had fallen down the back of a drawer in another IKEA cabinet and was slowly getting bent out of shape in there as parts of it eased out the back where the particleboard rear had come loose, as happens with IKEA cabinets, which is how I managed to find it, noticing the weak pleas for help from those few escaping pages - I'm wondering
will I get my umbrella back now?
I mean, I've fulfilled my obligations on that front. I've stopped looking, and I've bought a replacement. But luck being what it is, I suppose it will be the sunscreen instead. I'm not nearly as likely to need that in fall.
