What should call that? I often go to work by bus in the morning,go back by metro .It is boring when you are waiting a bus,then I find a solution that is reading. In the moring ,I was waiting a bus when I saw a woman.She was curious .She said :" are you study english?"then she said russian to me.I couldn't understand what she said.After she told me that she knew russian,and she was retired .She was a doctor.We started a conversation.we took the same bus .I am not local,we are from the same hometown.what should call that?
