text: Kate: you home?
  Caroline: No, why?
  Kate: Oh, I'm just in the neighborhood and I thought we might grab a quick cup of coffee or sth.
  Caroline: That''s a pity... I'll be back in 2 hours..
  Kate: OK, next time maybe :)
  Caroline: definitely!
target: Caroline will be back home in 2 hours, so she won't meet with Katie who's in her neighborhood right now.
