Input: Context: 'I'm good to give up firewood for more water and food.' 'Thanks!  You can have all the extra food. My pockets are jammed full of munchies.  But water is something it seems we both really need.' 'I'll do 2 water and 0 firewood, 3 food.'
Utterance: 'Hey, good news!  My site is next to a vending machine.  Mostly Ding Dongs and Ho Hos, but there is a bottle of water in there.  I can go with your recommendations.  I'll take three firewood, 1 water, and no food.  But I may be by your site later to borrow toilet paper. OK?'
