  #Person1#: What are you going to do there?
  #Person2#: Some people are in great need of help after the flood. Being a doctor, I have the responsibility to help those in trouble.
  #Person1#: That's true. But you often go to those dangerous places and we are all worried about your safety, mum.
  #Person2#: Don't be so troubled. I'm a doctor. I know how to care for myself. What worries me is your life and study at school. Are you used to the life in the school?
