Hi Shil1978, thanks for inviting me to answer your question.
I've been teaching English as a private teacher for the last five years in Buenos Aires. My experience has been really good in general; I've met interesting people, in and out of the classroom. All of them were eager to learn English (well, almost all of them). Usually, they're interested in English because they want to travel or work abroad, so they ask for conversational English, but I've also happened to come across people who just love the language and want to polish their pronunciation skills, grammar, etc.
People are warm here. Classes tend to be relaxed, jokes come and go, it's almost like teaching English to friends, and somehow that's what it ends up being. I always try to vary the topics and methods so my pupils don't get bored. One of the things I like is using music as an inspiration to hone their listening skills, or reading short stories, which I encourage them to write, too.
Today, I have many different kinds of pupils: from an old man who wants to be able to read Shakespeare, to a lap dancer who needs English as a professional tool, so to speak.
I hope this answers your question.
Thanks for asking!
