text: Alice: Good evening, Professor, I apologize for writing to you on Facebook but I thought that it would be the easiest and quickest way to contact you. I would like to ask if there have been any news about tomorrow's classes. Everyone is wondering whether they should come to the university tomorrow or not. Thank you in advance for any information. Kind regards, Alice
  Margaret: Good evening, all classes will take place according to schedule tomorrow, so no good news for the students! :) By the way, I would really prefer if students wrote to me on my email address.
  Alice: I know, I apologize
  Margaret: Ok, just remember in the future.
  Alice: It's just we got used to communicating with Dr. Smith via Facebook, he uses it all the time
  Margaret: I know, Dr. Smith has a very informal approach, however I happen not to share his views.
  Alice: Ok, sorry again, Professor!
  Margaret: You know I only answered here because you are older than your fellow students, had it been one of the others I would have told the rascal to send me a proper email message. ;)
  Alice: I know, I apologize once again
  Margaret: No problem, see you tomorrow!
  Alice: Have a nice evening
  Margaret: You too.
  Alice: Oh and may I ask you one more thing?
  Margaret: I feel like I'm being forcibly Dr. Smith-ized here.
  Alice: Sorry again...
  Margaret: Ok, ok, just ask.
  Alice: May I ask you if you have read the second chapter of my thesis? I hope it's good but I'm not sure...
  Margaret: I haven't read all of it yet but it's pretty good so far. I will send you more feedback over the weekend, ok?
  Alice: Ok, thank you very much, Professor!
  Margaret: You're welcome, just use email next time, please.
  Alice: I will! Kind regards
  Margaret: That sounded strange in a messenger chat, but ok. Yours faithfully!
  Alice: Good night, Professor :)
  Margaret: Good night, Alice!
target: Margaret is going to teach her classes tomorrow according to schedule. Margaret prefers that students write her messages on her e-mail address instead of Facebook. Margaret hasn't read the whole 2nd chapter of  Alice's thesis yet, but thinks it's good so far.
