Won't You Be My Neighbor?

Yesterday, in class, I asked my eight and nine year olds if they knew who Mr. Rogers was.  They, not surprisingly, had no idea. 
I almost started to cry.  Honestly. 
I can't help but think (and pardon me, as I sound as if I'm 95) about how much simpler our world was when we were kids.  I'm not saying that he could solve all the problems in the world.  I'm just saying that it would be a start.
