text: Vivian: what's the title of this movie - it's really famous - when in the end it turns out that the protagonist was a ghost all along?
  Liv: if you mean a movie with Nicole Kidman it was called "The others"
  Olga: or if you mean a Bruce Willis movie it was "The sixth sense"
  Vivian: " 6th sense! That's it, thank you!
  Olga: haha, you're welcome
target: Vivian forgot the name of a movie, in which the protagonist turns out to be a ghost all along. Liv proposes the movie "The Others". Olga proposes "The Sixth Sense". The latter is the one Vivian had in mind.
