I wish I had received a primary education like yours, Anno. At my useless Catholic elementary school in the 1940s, all we learned was the catechism, much of the New Testament, hymns and prayers in Latin (without translation), arithmetic up to long division (no fractions or decimals). The only geography, history or science I knew was learned at home by voracious reading - luckily, my parents were both avid readers.
Once I had learnt all the school was prepared to teach me I spent my last year marking the sum books of other pupils. But at least I still know the Cardinal Virtues, the Seven Deadly Sins, the Fruits of The Holy Ghost, and the sacraments. Very useful in trivial pursuits.
