Same here. After watching it and then looping the "Boldly in the Pretend" (official song to "Rain" music), my attitude to parenting and many specific behaviors changed pretty much overnight.
(For one, I realized we're both too harsh about kiddos getting dirty and making a mess. The other big thing was, it made me decide to make playground after kindergarten a priority more important than work.)
Beyond parenting, that story and song connected me with my own inner child, and had me realize I might be taking this "adulting" thing way too seriously. Work, play, it's still the same game - we're still just "racing those boats down the road to the end".
Can't think of anything else in my life that managed to break me down and put back together differently so quickly.
