My Guard
I tend to grind my teeth while I'm asleep so I have a guard. Well, I can't find it. I vaguely remember being half asleep and taking it out of my mouth, but I don't know where I put it. I've looked under my bed, looked through my bed sheets and all the nook and crannies around my bed. I can't find the damned thing. I've never walked in my sleep so I'm pretty sure that I didn't put it it in some obscure place that I'll discover later when sorting through my crap to sell in a garage sale or something.

This is just too weird.

Now, this means I have to call my dentist and get another guard made. This is all fine and dandy, but that missing guard will haunt me for the rest of my days.
