and let me just add an actual comment: you show the specifics of one child, defaulting to what a kid considers "the very important business" of their everyday. that's why it's a perfect take, we all start as little people. [:
I find it amusing how you say more about childhood in two short sentences than most kiddie films and TV shows combined. It's perfect the way you mesh something we recognise from childhood ("swingset") with an adult anxiety ("traffic is slow") and then pull the rug out from underneath it all through a blase last line that drags us back into innocence again. It's funny, too.
