The teacher that answered to your message is right because the most easy way to learn english is to talk with other people in english!You don't need the person you talk to in english to be english but he or she can be from other nationality!For example he or she can be Chinese but to know english perfectly!I talk in english with my sister who knows it perfectly!She studies in an american college and she talks like an american although she is bulgarian!I know a lot english but I am not perfect in it!I study english in a bulgarian school for foreigh languages!But trust me the teachers there are professionalists!
