Yep, I've been living in Sweden for 10+ years and have (embarrassingly) not learned Swedish to a native level yet.
The more I learn Swedish, the less ignorant I become to the advertising and "gotcha" headlines on newspapers and stickers and such; and I'm noticing its outsized (negative) effect.
I'm curious as to what prevented you from learning it to a level that doesn't embarass you?
Time goes by quickly and suddenly it's been 10 years is a perfectly fine answer.
