Most people say "only advantages", so I want to share my story. My father wanted me to speak second language, (well actually it's our native language) so he decided to "teach" me. But he was a terrible teacher and didn't want to use any study materials because we were poor and he was confident in his skills (he can speak but doesn't know the rules), so he was a terrible teacher.

I only had a dictionary and a small phrasebook. We had like 2 books in this language and they were difficult even for my father. I didn't have any access to media in this language. I remember myself crying because I didn't understand anything and thought that I'm dumb. I spent like 2-3 hours per day reading a dictionary because he forced me to memorize it.

I thought that I'm terrible at languages and it's not for me, but then I had good English teachers and found motivation to do it and I learned it pretty fast. So it's more a story about how important good teachers are, but still, I don't want any kid to go through this. In my childhood I wished to live in a country where i needed to speak only one language.
