text: Jeff: Hey did you make it to the Polish lesson last night? I came down sick with a severe cold and may miss the next lesson too.
  Rita: I'm sorry that you are sick! Hope you feel better soon. Yes, I went to the lesson. A lot of people didn't show up actually.
  Jeff: Did I miss much?
  Rita: You did, unfortunately, but I can help you catch up. We learned about the instrumental case?
  Jeff: The what? 
  Rita: Don't worry about it now. Just get better. 
  Jeff: Thanks, Rita. I'll see if I can read about it in the textbook when I get a chance.
  Rita: Sounds good. The book explains it very clearly, so I don't think you'll find it too confusing.
  Jeff: Ok, great. 
  Rita: Just so you know, the professor may have to reschedule the next lesson due to personal reasons. She said she'd let us know by email if that happens.
  Jeff: OK, thanks for the heads up.
  Rita: No problem. Hope to see you soon in any case.
  Jeff: Likewise. Take care!
target: Jeff missed the Polish lesson last night, because he got sick. Rita will help him to make up the lesson. The next lesson may be rescheduled.
