  #Person2#: Good morning, Miss White. You are half an hour early.
  #Person1#: I don't want to make a bad impression.
  #Person2#: Come on over. This is your desk, and this is your time card. Be sure to clock in and out before and after you work.
  #Person1#: I will.
  #Person2#: One more thing, keep your desk neat. It's the rule. There is no exception, even the art designers have to keep their desks neat.
  #Person1#: I'll keep that in mind. Does everything on the desk belong to me?
  #Person2#: Not belong. You can use them as long as you work here. When you quit, you'll have to return them to the company.

  #Person2#: The operator will put all your calls through. You don't have to worry about that.

  #Person1#: I understand.
  #Person2#: When you settle down, I'll show you around and introduce you to the department managers.
