You Just didn’t have Good Karma.
It looks like Karma was there to teach that child a valuable lesson on that day. No one knows how long ago it was, but if this guy can remember it so well, it must have been a big deal for him when he was younger and still figuring out who he was. It’s clear that the things he’s been through have helped him grow up.

Karma was the one who had something to teach him that day, not the girl who had been hurt or her friends. The only reason for a person to keep living. There was a stronger force at work, and it was trying to teach him a lesson any way it could. What do you think caused this event that seems impossible? This piece of information is very encouraging because it seems to show that the message was heard.
