  Matt: Back where?
  Kasia: Oh come on
  Kasia: you know what i mean
  Matt: I really don't 
  Kasia: When are you coming back to Warsaw
  Matt: I have no idea
  Matt: maybe around easter
  Kasia: will you let me know
  Matt: sure if I know something then I will let you know asap
  Kasia: ok 
  Matt: are you mad?
  Kasia: a bit
  Matt: oh come on
  Matt: this is not my fault 
  Matt: there is no way that I can answer that question
  Matt: not now
  Kasia: Fine
target: Matt doesn't know when he's coming back to Warsaw. He might come around Easter. When he knows more, he will let Kasia know. Kasia is a bit upset.
