Intertwined and Why?

You ever notice how you run into people that you know occasionally, but it always seems like the same people, over and over again? Why the heck is that?

And you know it most likely isn't anyone you would choose to see. I would love to run into my buddy Kenny or Brian from high school, but no. I'll see someone who I have no interest in seeing. Over and over. It's like groundhog day, the movie with Bill Murray. (I love that movie. Transformation of character is the best underlying plot, I think)

So here it is. This is a feeble example, but I knew this kid, Larry, when I was growing up. Now, if you read many of my blog entries you are thinking, another fucking Larry? Not even a pseudonym, oddly enough I have known I think 4 or 5 Larry's in my life.
Anyway this Larry is like a bully-type, but we are sort of friends. We went fishing together a lot, and he would catch the tiniest fish, keep them and eat them. I'm talkinga filet the size of a quarter. Weird.

Maybe five years later I run into him on my way to basic training at a bus station. He's on his way to juvenile detention or something. The start of his criminal career. This is the guy I see every ten years or so. I read about him in the paper, latest crime, picked up for X, whatever.
When I see him occasionally in public, I don't talk to him. He probably doesn't recognize me, but I have a great memory for people. Not always names, but faces and stories I remember.

So why is it that we see people like this? Is there some intertwined destiny? This guy doesn't want my help. Am I supposed to learn something from him? I don't know. Maybe the last appearance will be the last time I ever see him. Or maybe next time I'll say hi.
