Context: 'I would like a little extra food for myself as well. Would you be willing to split the food 1 for me and 2 for you? ' 'I'd be willing to do that if you gave me some water and firewood in exchange' 'How about I keep 2 firewood, you take 1? What do you propose for the water?'
Utterance: '1 food for 1 firewood isn't a good trade for me. I would need at least 1 firewood and 1 water to trade for 1 food.'
