My socks. Sometimes, when I wash my clothes, I find one of my socks are missing. Always a sock. Why? The best I can figure out is that an Alien must have taken them. Where else could they be going? I've tried to figure it out but evidently there are invisible Aliens that are in peoples homes and they are taking our socks, one by one. Maybe it is a game of "scavenger hunt" they are playing among themselves. What do you think?
