I was educated in a private school for British ex-pats run by a very old and very posh couple. This was the early eighties and they were already in their seventies, so definitely from a different era. Because of this and because of the size of our school (my entire year consisted of nine kids) we ended up quite odd. Up until highschool we had a mild but "poshy" London accent and words like vexing, nonplussed, providential, etc., peppered our vocabulary. Then my family moved to Louisiana followed by Texas and that shit went right out.
I very recently learned that Amour is not universal and I just grew up playing a singular RPG that was developed by a group of British brothers so that forever shaped my expectations for how Armour should be spelled
