  Cindy: Good morning! :)
  Leo: How are you feeling today?
  Cindy: Way better
  Leo: Ok... I'm so sorry about what happened
  Cindy: It's ok, Leo, really
  Leo: Are you sure?
  Cindy: Pretty sure :)
  Leo: Well, ok...
  Cindy: Marcy also said nothing terrible happened
  Leo: Ok!
  Cindy: We just had bad luck, it was not your fault
  Leo: We still had to walk for two hours in the snow :/
  Cindy: You couldn't know your car would stop all of a sudden, come on
  Leo: Yeah, I know... but I still feel guilty
  Cindy: You shouldn't ;)
target: Leo feels guilty about his car breaking down in the snow, so he apologized to Cindy.
