text: Victor: do you need me to pick you up from the airport
  David: that would be neat
  Victor: what time are you landing
  David: 17:30 at Sevilla
  Victor: SEVILLA???
  David: yeah sorry
  David: Jerez was too expensive
  David: you don't have to pick me up if you can't
  Victor: no its ok
target: David is landing in Sevilla instead of Jerez at 17:30 as it was too expensive. Victor will pick him up from the airport.
