text: Sam: I have sent you the invoice for last month.
  David: Thanks! I'll check it later.
  Sam: Also I think it makes sense to part ways after this month unless you can find someone to replace me sooner.
  David: OK. Why do you want to leave?
  Sam: Originally you said that you can provide me with 80-100 hours per month but it's never been more than 50 pcm.
  David: ...
  Sam: ATM it is even less. It's not really viable for me when all I get from you is about 5-6 hours per week spread over 3 days.
  David: I see.
  David: If you want to leave that's fine. We have been looking for someone to replace you in the meantime anyway.
  Sam: OK. How soon do you think you can release me from the contract?
  David: Hopefully next week.
  Sam: When will you know?
  David: Next week. :-)
  Sam: OK.
target: Sam wants to end the contract with David. In the meantime David was already looking for someone to replace Sam. Hopefully Sam will be released from the contract next week.
