documents: #Person1#: Well, Lucy. Why do you look unhappy?
  #Person2#: Oh, Mike. I've made 3 bad mistakes so far this week. This morning I forgot to give a very important message to my father, so he got really angry with me.
  #Person1#: But you're usually very careful and never make mistakes. What's the matter with you?
  #Person2#: I'm very tired. I don't know what I'm doing these days.
  #Person1#: Have you gone to bed late recently?
  #Person2#: I'm usually embedded about 10:00, but I have been woken up at 4:30 every morning. And then I can't go back to sleep.
  #Person1#: Why?
  #Person2#: It's my new neighbor. He has to get up at 4:30 every morning and he always turns his radio on loudly.
  #Person1#: Ask him to turn it down then.
  #Person2#: OK. I'll have to talk with him.
