Umbrella thief.

What is it about umbrellas that make they mysteriously disappear constantly? I must buy a half dozen or so a year and never seem to have one when I need it. The weather we are having right now makes me really wish we had one of those carports to pull under since all of my umbrellas are missing. I think someone takes them to work and they never make it home. Either that or we have a sneaky thief who loves umbrellas from the dollar store.
