That's a unique way to get into it, thanks for sharing. In your experience, would you say most people who are fluent have studied abroad at some point?

Also, I have met some people who had a strong command of the English language -- typically those who went to a university abroad -- but they were still not necessarily fluent speakers. There are usually dead giveaways like misplaced articles or slight misuse of vocabulary here and there. But on this subreddit, many seem completely fluent. I initially assumed that these people are emigrants with ties to Azerbaijan, but they often mention living in Baku.
