For me it's the forgetfulness around this that really grips my shit.
I lose things because I forget where I've put them, or I forget what I was doing when I last had them. My brain just goes off on its own little track, regardless of what I need it to do, then BAM, I can't find something that my wife is asking me for.
Completely randomly yesterday, I interrupted something she was saying to me to blurt out where I put the cats' Dreamies, because I suddenly remembered that I'd put them in an out of the way place so they wouldn't get to them and tear the packet up. If I'd waited until she'd finished talking, I'd have forgotten, then we'd never have found them again.
