I spend the 6 week summer holidays with my children, it's how our own personal family set up works.
They have late night, late mornings, routine mostly heads out the window. We spend endless days at the beach with cousins, theme parks, rivers, playing football in the park. The housework gets put on the back burner, reading and maths is thrown out the window. We go to places where they're learning about the local area or just learning life lessons, how to behave socially and interact with others.
But come the end of those 6 weeks, i feel sluggish, I'm tired, my drive to do things is gone and however much I miss the kids, I'm ready for them to head back to school. They are too, not because of boredom but because they want to see friends and go and chat to their teach about the starfish they found, or the massive stick they carried 6 miles and then wouldnt fit in the car.
Those kids though live that sluggish, late night, late morning life endlessly, there is nothing else, no routine, no prospects of seeing friends just living in an insular bubble. No wonder they look the way they do and churn out endless drivel, they have nothing about them.
