text: Henry: What's the entrance code?
  Jessica: To the lab?
  Bobby: 7898
  Henry: This is what I thought but it doesn't work
  Bobby: That's strange
  Bobby: It worked yesterday
  Jessica: They sent us an email yesterday that they would be reseting the system
  Henry: Oh no! Today?? 
  Jessica: I'm afraid it's today
  Jessica: But maybe you can talk to the administrators to let you in if it's urgent
target: Bobby gives Henry the entrance code but it's invalid. This is due to today's reseting the system but Henry can still contact the administration.
