While showering yesterday, I heard the back of one of my earrings hit the shower floor. I picked it up and placed it on the vanity outside of the shower. Thought nothing of it again until this morning when I remembered and immediately went to make sure the earing didn't fall out overnight. To my surprise, all 12 of my earings still had their backs snugly in place. Did I hallucinate it falling out? Did I put it back on and not remember? I went to the vanity expecting to see nothing and lo and behold there's the earing back that fell out. I'm at a complete loss. I don't have extras of these laying around, each earing has 1 back. All my other earings with their backs were inside my jewelry case, all matched up. The shower is tiny (corner stand up thing) and bright white. It gets rinsed after each use, and i just did a good scrub of it a week ago - there is no way that a lost back from another time could have still been in there sight unseen. These are flat back screw on kinds, and no one else in my house where's ones like it. It makes the list of top 5 unexplained things I've experienced in my life.
