child pick-pocket

Today at a swim meet I was talking to other people on my team. One guy told me that apparently, there was a 5-year-old pick-pocketing child wandering around. So I'm like umm. . . okay, because, a) I don't think there usually is a lot of pick-pocketing going on and b) the kid is 5 and c) it's a swim meet. He was telling me how the kid would sometimes go up to adults and say hi. They would ask if she was lost or needed help, and the kid said "I'm fine. But can I see your wallet?". Creepy.
