I'm pretty bad at losing stuff, but generally short term, in my flat.  My armchair and the area around it seems to be some kind of black hole for my stuff.  The leather sleeve I keep my phone in, rings, bits of paper, earphones, my wallet, all have the ability to hide in plain sight (or under things they shouldn't be under) and remain there until minutes, hours, days or occasionally weeks after I'd given up on finding them.  I get a small amount of satisfaction from knowing, each time, that I'd left them in a safe place, but mostly it's frustrating.

At this point, those of you who thought this thread was about figuratively losing your shit will also be a bit frustrated right now.  Sorry.

Boarding the flight leaving Las Vegas, Delta airlines staff were letting loads of passengers flagrantly breach the rules about the size and weight of hand luggage.  They were asking people to voluntarily check-in their hand luggage, because they clearly regularly run out of room in the overhead lockers.  It's clearly also their fault, but they like to nevertheless threaten those of us getting on the plane last with having our bags taken from us, despite it being other people breaking the rules.  So, given that various selfish arseholes had used up all available space near our seats, I had to put our bags in overhead bins quite far from our seats.  This then meant that disembarking was quite stressful, struggling through sweaty morons dragging apparently lead-filled suitcases out to drop on any head or shoulder in the vicinity, just to get our little rucksacks and then run the gauntlet back the way.

After grabbing a bite to eat at Atlanta airport, we waited at our gate.  A wee while later, I decided to get my stuff ready for the next flight.  That's when I realised that my Kindle was not in my bag, but in the seat-pocket in front of my seat on the previous plane.  In the stress and hassle, I'd grabbed everything else to put in my bag, but not the Kindle.  Now, I'm not trying to say it's Delta's fault, it was my fault I lost it, but I'm miffed at the circumstances that led to it.

I had enough time to get to a Delta desk to report it, but by that time the plane we had been on was en route to Orlando, and I had to board my next flight before I was able to hear anything back.  I've reported it via their online lost and found, and I don't see why it shouldn't show up, but I'm not holding my breath.

Are you bad at losing stuff?  Do you regularly properly lose things, or like me do you temporarily misplace trivial things?  Or are you somebody who never loses anything, and gets annoyed by other people's carelessness?
