My partner is always whining about the amount of socks of his I lose so I tell him this.. They had to be separated because they wouldn't stop fighting & trying to hurt each other, then all the mismatched socks made a pact & ran away to the laundromat to be with their cousins... Maybe this is what's happening to you too :)
It's a well-known scientifically established fact that washing machines do not run on water and electricity. They eat socks to maintain their strength and health. And those little dust bunnies behind the washer? That's washer poop: sock lint!
I have stayed in many countries for periods of up to one year, and found the same effect everywhere. In the Pyramids, and in the Bayeux Tapestry, you can see individuals wearing only one sock. We did an experiment, an engineer checking the machine through in front of two witnesses, then an independent person putting in socks which were counted as they went in. Sure enough, one less came out, and the engineer said it was nowhere inside, although he did a bit of taking it to pieces. We, (a group of scientifically-qualified adults) came to the conclusion that it is either some alien phenomenon, or related to the quantum word and/or the multiverse ... as we were having a drink afterwards.
