One of the great thrills of my life (not really!) was having my English-as-a-second-language Swedish in-laws ever so condescendingly "correct" my pronunciation. I don't know how many generations (several!) of my family have been exceedingly careful with their use of our ages-old language � English � while also well acquainted with Greek, Latin, French, German, and other languages.
My in-laws settled in Minnesota, and I was born in Alabama, so it's understandable that they were automatically vastly superior to me in all ways. They certainly made that clear at every opportunity.
