I also worked with Swedes. Some of my Swedish friends tell me that I've never met a Swedish extrovert. If Swedish introverts run naked down the halls after a few gallons of glögg, I'm not sure I want to meet an extrovert. I already have 5 grandkids.

Speaking of how languages sound, I’ve watched a number of Swedish movies recently. The me Swedish sounds very much like English, if you don’t pay attention to the words.
Certainly much more so than German, French or Spanish.
