text: Alex: Hi, I just wanted to tell you that I've made you a termin by the dentist
  Olaf: Oh cool I wasn't there for a while
  Olaf: when is it?
  Alex: On Thursday at 5 o'clock
  Olaf: Oh no I wanted to meet with Ellie then. I'll call her if she can make it later
  Alex: You have to move that meeting cause the dentist is full and you won't get a termin in the next month
  Olaf: Okay I get it, it's important
  Alex: Good, I'm gonna pick you up at 4 and we go buy you some shoes. Is that okay?
  Olaf: Yeah that's good
target: Olaf has a dentist's appointment on Thursday at 5 so he needs to cancel his plans with Ellie. Alex will pick Olaf up at 4 to buy him some shoe first.
