That's a signal
After watching this, I just remembered the event. Man, it's IMPOSSIBLE not to remember! This flash MUST have something to do with that!
That kid definitely wasn't normal. I'm not sayin he was a psycho or a retarded, but the point is something was veeery wrong with that fella. I don't know if it's the case of calling him "a product of an alienation culture", but the point is that guy needed help. And whoever he asked to do that failed miserably. Please, don't think I'm blaming his family, friends or whatever. But he needed something/someone desperately, and that's the problem. Pay more attention to your kids, pals...cause I'm paying attention to mine.
