When I came in she was playing the piano. And she said she had been playing for 2 hours already.
We were going to the institute when we met him yesterday.
Mother answered she had been doing the flat for an hour but she was afrad she wouldnt be able to have finished it by their arrival.
What were you doing when I rang you up yesterday? - I was doing my lessons for next day.
I saw she was writing something and decided not to disturb her.
