My Left Shoe has a Curse

My shoe, untiedHere at work, I sit in a desk. I don’t get up and move around all that much; I’m mostly stationary. Yet, somehow, by some magical and mysterious way, my left shoe always comes untied. It probably happened 2 or 3 times here at work yesterday, and I left at about 3. Between then and coming back to work today, with all the walking and driving and taking shoes off/on (I slip them on) it never came untied. Now here it is, 12:30, I’m at work, and magically it’s untied now. I don’t understand this. Someone explain this to me!

UPDATE: It’s now 3:22 and… it’s untied again. I haven’t left the building, I’ve walked to Troys desk maybe 3 times… help me!!!
