text: Elisa: I'm going now to the city centre, anybody wants a lift?
  Kate: if you wait 15 min, I'd go with you
  Jennifer: Same!
  Elisa: why 15 min?
  Kate: I just washed my hair, don't want to get sick
  Jennifer: I'm finishing something 
  Elisa: gosh, I have to be at 3 at the central station
  Kate: shouldn't be a problem if the traffic is fine
  Jennifer: and it should be ok before 3
  Elisa: but if not, I'll miss my train
  Elisa: sorry, I am afraid I have to leave now
  Elisa: I'm too stressed
  Kate: Ok, I'm coming
target: Elisa's going to the central station. She has to be there at 3 pm if she doesn't want to miss her train. She'll give Kate a lift to the city centre.
