Answer to Lisa's Key Mystery

I have long had a theory that there are two kinds of people: those who lose keys and those who find them. I am a key loser. I have actually dropped a set of car keys in the parking lot, bent over to pick them up and discovered they had disappeared. This did not surprise me, since I have been unable to stay in possession of a single key since my parents gave me my first one to our front door.
No matter how many precautions I take, my keys refuse to stay with me. On those few occasions I have actually managed to keep one, it won't work when I insert it into a lock. I have been shut out of my own house so many times, I no longer lock the door when I leave. (Note to prospective burglars: don't bother, there isn't anything worth stealing).
I believe there is a fifth dimension where lost keys go...they stay there for awhile, then appear in someone's drawer, on a key ring, or at Lisa's house, unidentified, unrecognized, unusable. It doesn't matter if you toss them, they'll always reappear if you're one of the finders. And it doesn't matter how many times you replace them, they'll always vanish if you're one of the losers.
Here's a mini-poll: are you a finder or a loser? I'm just wondering if the numbers are equal. If not, that fifth dimension should be either clanking with keys or echoing in silence. I'd love to know which it is.
