Do you ever go to look for your wallet, and it's not where you KNOW you left it? Yeah, it's possible (probable?) that you're just being a bit forgetful, but it's ALSO possible that you and Murdoch have something slightly terrifying in common!
But just be glad that a misplaced wallet is the worst of your troubles. You could be caught in a hailstorm of boulders if you're really, really unlucky!
