text: Pete: What flavour yogurt did you want again? My brain is like a sieve today.
  Jen: Pear but only if they've got it. Otherwise don't worry about it.
  Pete: I'll have a look around. If they don't have pear can I get a different flavour?
  Jen: I don't like any other flavour. If they don't have pear just don't get anything at all then.
  Pete: OK.
target: Pete will get a pear yogurt for Jen if they have it.
