The brain is an amazing organ.
Just occasionally though, mine could do with a pause button.
A couple of days ago, I was searching for - actually, I'm not sure of the name of the thing. It's like an embroidery hoop, but has a solid insert. It came with a kit when I was into Hobbytex about a million years ago, and is useful when fabric painting. Let's call it the hoopish whatchamacallit (huh! spellcheck doesn't like "hoopish", but is just fine with "whatchamacallit"!). So, the whatchamacallit wasn't in the craft half of the wardrobe, or in the project pile. Hmmm, don't think I tossed it out. Scratched my head, got distracted by something else, wandered off.
Cut to 3 a.m. the following morning. I jolted wide awake with this thought in the front of my mind: "The whatchamacallit is in the white chest of drawers in the spare room, third drawer down on the left hand side, with the fabric paint."
The search mode had evidently been ticking away in my subconscious for more than half a day, had located the requisite memory, and dropkicked it into my conscious mind, waking me from a lovely sleep in the process.
Thank you, brain, that was useful information (and yes, it was right, the whatchamacallit was exactly where it said), but I could have waited till morning for that little bulletin.
