I learned (some) Swedish at age of 35 and it was quite a moment when IKEA product names became meaningful to me. Plate PLATE, fun!
Pretty much like when as a kid I learned enough of English to realize all those songs around actually have lyrics, pretty dumb sometimes
My first memory of being angry with not knowing English was when we were trying to read the pokemon or Yu-Gi-Oh cards and I clearly remember it being gibberish. Otherwise it's difficult to remember what it was like to not know a skill before you learned it, at least it is for me.
