This morning I found one of my earrings (that I wear to bed - I know - I'm
lazy) was on the floor next to the bed WITH the back attached to the post.
The hole in my ear is intact. Hmmm - somehow the earring just migrated from
my ear to the floor without having the back removed!

Of course, the other possibility is that I was half-asleep, took it off, put
it on the nightstand, and it fell to the floor. But I'm thinking it was
alien intervention myself!
