Sorry for how vague this is but I figured it was worth a shot.
I'm thinking of a film which could be made up haha. It's about a family and I am sure they end up travelling or something and the dad teaches the children how to grow up but in a non child friendly way.. Like teaches sex ed but very honestly rather than child friendly terms. And basically doesn't sugar coat everything in their childhood. Sorry it's vague but if anyone has any ideas! Thanks
