I grew up in Estonia, speaking Estonian. When I was nine, my dad moved to Sweden and after about 6 months me, sister and mum went to visit him. I knew that in Sweden people spoke Swedish, so I was convinced that once we'd get off the boat in Sweden and met dad we would all speak Swedish to each other and understand it perfectly. And when we returned to Estonia we would speak Estonian again... When we actually arrived I was very confused as to why we still spoke Estonian and, worse, why I couldn't understand what other ppl around me were saying....
