  John: actually in 5
  Sam: Should I pick you up or you'll manage to find the address?
  Lia: Sam, pick him up
  Lia: it's too far
  John: don't bother I can find the place if you send me the address
  Lia: no, it's too cold and too far, Sam will be there
  Sam: I can be there, but you have to wait 15min at least
  Sam: also it's not easy to park there, so it would be nice if you stayed outside, so I could just pick you up
  John: ok, I will wait at the bus stop
  John: I have a big black suitcase, you can't miss it
  Sam: perfect!
  Lia: let me know if everything is ok
  Lia: I won't be home before 7, unfortunately 
target: John'll be at the main station in 5 minutes. Lia suggests that Sam should pick John up. Sam'll collect John from the bus stop in 15 minutes.
