I don't lose things, I temporarily misplace them. But my dad on the other hand, he spent some time helping us renovate our house and he lost every single tape measure that he had - and he had quite a few. He never found them and while a part of me is sure they got closed up in some wall (or walls) another part of me is sure the ghost in my house used to be a carpenter and he wanted them for himself. I officially have one tape measure and I will only keep it in one spot and it hasn't been lost (or temporarily misplaced) yet.
My damn wallet ALWAYS is disapearing, sometimes days on end. I should probably just keep it in my back pocket like everyone else. Sometimes I put it in the back pocket, sometimes I put it in my coat, sometimes I carry it to the car and put it in there. Its almost daily that i'm looking around, searching for it.
My keycard to get through the lobby barriers at work - I sign in more then clients visiting the firm.
I live in a dorm, so I have to use the dorm laundry. I'd guess that I've lost/had stolen at least 5 T-Shirts, 2 dress shirts, 2 hoodies, and a pair of shorts. Countless socks on top of that because those fuckers always fall in the hallway without me noticing. Fuck the person that keeps stealing my laundry. What a prick.
I have been married six years and am on my third ring. I cannot for the life of me keep up with a wedding ring.
I think I was the one stealing all your lighters. Whenever my roommate and I got home from a bar, we'd go to light a smoke and pull out some color of lighter we didn't leave home with. Both of us did that without intending to nick them off people. We kept a bowl of them on the table for people to claim or take. So, on behalf of lighter thieves in bars, sorry!
I also use campus laundry facilities. I haven't managed to lose actual shirts and pants yet though. Usually I'll lose an odd sock because it's sticking to the top of the barrel (side loading washing machines) and the tards that remove my laundry in a rush to do their own don't care enough to check. On the other hand, I've managed to get at least a dozen mysterious socks and one shirt in my laundry that are not mine. I ALWAYS check the barrel to make sure it is empty before I put mine in. There's apparently a huge vortex that takes your missing socks and deposits them in my laundry. Awesome.
