text: Lizzy: Hey, can you take notes for me in Biology tomorrow?
  Amanda: Umm... where are you going to be?
  Lizzy: I have a doctor's apt tomorrow at 9.
  Amanda: Ok, sure. No problem, except you know how Professor Gray gets when he sees someone away.
  Lizzy: If he mentions something, let him know. I'll talk to him next class. I have to see him about something anyway.
  Amanda: Ok
  Lizzy: Thanks.
  Amanda: Are you sick?
  Lizzy: I have to get something checked out, that's all. And I finally got an apt to a really good doctor.
  Amanda: Ok, tell me about it tomorrow.
target: Lizzy will miss the Biology class with Professor Gray because of a medical appointment. Amanda will take notes for Lizzy and explain her absence to Professor Gray if needed. Lizzy will talk to him after next class.
