I am sure everyone has heard or believes in some theory which explains why some things in life simply insist on happening. Let me give you an example: The sock fairy. It is a fairy who flies through people's bedrooms, stealing one pair of their socks and magically disappearing, while leaving its owner wondering if the missing pair of sock can ever be found. No one has ever seen a sock fairy. But there is plenty enough of evidence that it exists. Just want to hear some other "theories" like that. I'm pretty sure there are plenty out there, so if anyone knows any, make the forum believe in it too!
