Those who weren't around when Mr. Rogers' Neighborhood was on TV may find it a little hard to understand why it appealed to us growing up.
A cursory glance at it would simply show a man sitting around and talking very softly and slowly before a little trolley took us to a puppet show. And while those puppets had personalities, they were often more low-key than what we would see from muppets like Elmo or Oscar the Grouch.
But the more that people understand who Fred Rogers was and he was about, the easier it is to understand why we loved and, let's be honest, needed him.
