text: Mike: who's going to the lecture tomorrow morning?
  Sean: i've never managed it, so I don't think it's even possible
  Joseph: I'm going but it's a nightmare 
  Joseph: how do you want to pass the exam Sean?
  Sean: you all make notes, don't you?
  Mike: we do...
  Mike: but there is a very important question: are we going to share them with you?
  Sean: nooooo.... how cruel
  Mike: we all like to sleep, but we keep going there anyway 
  Sean: I think I like to sleep more
  Sean: I'm just unable to get up so early
  Joseph: so are we!
  Joseph: Try at leat once, then we can think about sharing the notes
  Sean: how mean...
target: Sean never gets up for the morning lecture. He needs to attend it at least once to get the notes.
