Shoe Fetish?

I noticed this morning that I am missing a shoe. They come in pairs and now I only have one. I wore them on Sunday, so I know they were here two days ago. They were sitting on the sun porch at the back door with about 30 other pairs of shoes.

These are not special shoes. They are brown McClain wingtips and I have grown rather fond of them in the 3 years I have had them.

Who in the hell steals one shoe? The back door is open during the day, but locked at night and guarded by motion sensor alarms and an IR camera. My wife and son swear they are not screwing with me and I have searched everywhere for it.

I want my fucking shoe back!
