The Case Of The Missing Skivvies

I was folding and putting away the laundry and got to the skivvies and counted one...two.
and counted again...one ..two.. there was supposed to be three of my favorite, blue and white striped boxers. Three.
Ah well, thought I. Probably dropped them in the bodega...no. Then maybe upstairs, taking them down from the line.....no. Ah, but then surely I dropped them going down the stairs....no. In the spare room...? No. Under the bed ? No. Nowhere in the house did I encounter my skivvies, and the problem is that I can blame nobody. There is only this person here in the house, aside from the Worthless Mutts, but even as worthless as they are, not even they would abscond with my undies.
So now I have to wait to the missing garment miraculously appear again and till then, this will remain the case of The Missing Skivvies.

Maybe there is a mischievous skivvy fairy in the house.
