I really, really, REALLY wish I knew! I don't have a clue. The irony is that it only happened to me. I am constantly bitching at my husbear because he is terrible at forgotting his wallet, walking away, and losing it. Me, on the other hand, I am paranoid. I always know where it is, and if it isn't with me, it is stashed away. The only way somebody could have gotten those cards would have been to have lifted them on the last day I was on vacation by getting INTO OUR ROOM (which creeps me out), or by going through my wallet while it was locked in my locker at the gym (which also wigs me out). In any case, it shouldn't have been easy, but it apparently was.
