Hello - OP here. I was helping at an event when this happened. First of all, I'd like to say that there was no way the kid just wandered off. His dad was in a parking lot looking for his stuff in his car at least 200 meters away. He just had his head up his ass. Second of all, I know it was wrong to not call the police or at least get some adult involved, but I'm only 14, and so I guess I wasn't jaded enough yet to realize any predator in the vicinity might see that as the perfect opportunity. For what it's worth, though, I saw a very close resemblance between the two, so at least that's something.
