[Q]: Context: 'I'm great! Just getting excited to go camping and dreaming of all the food I'll eat! Do you have any extra food?' 'Let me ask you, do you need food most? If yes, what do you need second most?' 'I would love as much food as is available. I would also appreciate excess firewood, as I get cold.'
Utterance: 'Okay, it seems we both have the same priorities in food most and firewood second most. How about this, you take 2 packages of food, I will take 1. You give me 2 packages of firewood I will give you 1. We will then divide the water. Is that fair?'
