Watching shows from your own childhood can make you feel old. But if that doesn't do it yet how about watching shows from your childs childhood?
Our son is visiting us and for some reason we ended up watching one of his favourite show from years ago. It was one of the better shows that I remember also watching without that usual dread for most of the children shows. The one that also works for older audience with some carefully hidden puns that you need some mileage to understand.
It was also some nice nostalgic moment sharing a common memory from his childhood. Makes me really appreciate those moments spent together back then. Maybe in another decade we can have another go with the same show and look back once again.
