Losing my marbles

Actually marbles is about the only thing I have not lost. Does anyone else go through periods like this, where you temporarily misplace items and despite looking everywhere simply cannot find them again? One minute there, the next minute gone. What makes this doubly frustrating of course is that I have not gone anywhere. The item in question is currently my sunglasses, and they must be in the house somewhere. But where?! I used to have two pairs, the first pair -  the nice ones - I lost in a bar in Tallinn last year. No bother, I've simply been wearing the old ones, but now they're gone too. I had been using them more with the advent of nice weather, in particular for skywatching. I had even put the eyecups of my bins down so I could more effectively use them with glasses on. Glad I bothered.

I have no idea (obviously) where they could be, and I have checked EVERYWHERE. Well, everywhere except where they are. It has almost got to the point where I am going to order some new ones, but we all know what will happen then don't we? On the plus side, I would be back to having two pairs again....

I have also lost my moth book. Like the glasses I saw it just the other day as I was tidying up a bookshelf. I had not looked at it for ages, but now that I have started mothing again I of course need it, and despite an extensive search it has not reappeared. You would think that there is an even smaller list of places where it could be hiding than my sunglasses, I mean I could have put those anywhere, but a book? Instead I am using various websites to identify things, but nothing beats being able to thumb through colour plates

An evening mothing. A mercury vapour bulb suspended over a white sheet, and then an actinic Robinson Trap. 

There is no substitute for sunglasses though. Every now and again I jump up with a shout and run off to where they must surely be, only to slink back to the dining table empty-handed. The family have been very supportive, all four of them constantly donning their shades in the garden, around the table when I come back from my latest abortive search...
