Going home only for lunch? The little me might not go back at school again if it's like that
haha
When something is a tradition and certainly when something is a routine tredmill.... thinking and choice are eliminated. You just do. No effort, no stress, just time.
The reason behind this all was that traditionally in the Netherlands the warm meal, potatoes, vegetables, gravy, meat and some pudding with (soaked dried) fruit as desert was eaten at lunch time. The whole family including working daddy.
This together warm meal eating, and Christian people together praying, thanking God for the good food, and Protestant daddies odten reading a page from the Bible, was an important part of family tradition.
My school hours were 9.00-12.00 and 13.30-16.00. I did walk a lot

(and hurried up eating my lunch to be early back at school to play football ofc before the lessons started)
People working, the daddies, had often 1.5-2.0 hours lunch time to be able to get home and back. And people living nearby took often a nap.
With shifts for factory workers, especially with the three-shift system this all changes over time, increasing commuting time from arising suburbses the firther drive for change. But for children this familymoment is still there. Whereby noted that this is shifting because both parents working happens more and more.
