teach us humility and gratitude

That's one aspect yes. I enjoy the story though, musing over what their lives might have been like, who they were, rather than trying to draw some type of learning experience from it all the time. Maybe I'm just a simple-thinking man, but I like to think about their lives. Sure, there's lessons too, but sometimes life should be lived a little rather than always seeking something. I believe that's where people go wrong a lot. They seek something ahead of them rather than living what's around them.

But what do I know I guess.

I agree that life should be lived. Many miss the opportunity of today thinking of tomorrow or of yesterday. Of course many people are seekers, but what do they seek and why? I guess this running ahead is a deflection from looking in the present, which for some might not be as peachy therefore they feed their imagination thinking something different will be ahead. But their mind is not ahead, is stuck on a wheel. In the end, it's a matter of attitude.

Yes, pretty well said I think.
