Bit of a random one. My eldest is 19 and it's only this year I've properly clocked how much genuinely useful "adult life" stuff just never gets covered in school - not because teachers don't try, but probably more that there's never actually time carved out for it.
I had to sit down and explain what a mortgage actually is and why an unpaid phone bill can damage your credit file for years, because none of that had ever come up in school. Also had the apprenticeship vs uni conversation recently and realised there's no real structured way for them to weigh that up - it's basically left to them and whoever they last spoke to.
So for full disclosure, I'm actually building something around this (a curriculum site for 16-25s) but not naming it here as I don't want this to read as a plug. I'm genuinely just curious what other parents experience has been around this. What's the thing your teenager had absolutely no clue about until they had to learn the hard way?
