  #Person2#: Oh, I am very sorry, Hans. Thank you for waiting for me. You must have been here a long time already. 
  #Person1#: It's all right. 
  #Person2#: I was caught in the heavy rain, or I would have come earlier. I am sorry I kept you waiting. 
  #Person1#: I was in a comfortable place, so really, it's no problem. I am happy to see you. Did the rain hold you up long?
