Some posts back I wrote that we are educating the children for a future we cannot imagine. That's a difficult concept, because of course it's hard to imagine what we cannot imagine!
Here's a British TV sketch you'll enjoy. On one level it's just a funny sketch; on another it makes us aware of how many words we use in ways that were inconceivable when we were children (that is, those of us who are over 35 now). And of course, there are many more concepts we use daily now, using words that didn't exist at all back then!
We live in a world that no-one could imagine, when we were kids.
