documents: #Person1#: Hi, Scott. How are you?
  #Person2#: Oh, hi, Rebecca. I'm tired.
  #Person1#: Well, don't go to bed so late.
  #Person2#: But I don't. I watch sports on TV and then I go to bed at about 9:15. The problem is I wake up really early.
  #Person1#: Why is that?
  #Person2#: I take the boat to school now and it goes at 7:30 in the morning so my mom wakes me up at 6:44. I have breakfast and leave home at 7:00.
  #Person1#: So have you changed school then?
  #Person2#: Yes. The school on our island is for 6:00 to 11 year olds. Now I'm 12.
  #Person1#: Oh, I see. So do you get home late in the evening?
  #Person2#: Quite late. The boat back home is 2 hours after school. My mom's sister lives near the school. So I go and have dinner at her house.
  #Person1#: When do you have time to do your homework?
  #Person2#: I usually find a quiet table on the boat. When I get home, I watch TV, listen to music or use the computer.
