Context: 'I want to go on hiking too. Since I don't go alone I need food and water.' 'I would be willing to sacrifice the majority of food in exchange for water and firewood.' 'This offer is good for me but I need some water too. Can we share the water and have all the firewood? 🙂'
Utterance: 'No, I offer you 3 food, and 1 water.  I would like 2 water and 3 firewood.'
