Sorry to hear about the new place

If you've only got two types of socks then you only ever need to yank out a maximum of three socks before you have a pair. You'd have to loose all but 2 to possibly have a no matching sock situation but hopefully you'd notice before you end up with only two socks

I'm just curious as to where lost socks go. I've got my own washing machine so it's not that I'm leaving them in the laundrette somewhere. If they were getting stuck to the inside of the washing machine then I'd find them the next time I did a load... If they were getting lost in my chest of drawers then I'd find a big ball of socks somewhere...
