question:
Context: 'Not bad, not bad. How are you. What's on your mind for camping? ' 'I'm doing well. We're desperately needing wood. We didn't realize how cold it would be as it is our first time here. There is none around our area so we are really concerned about staying warm especially at night. We also forgot a bag of food, so that's another need for us.' 'True. Turns out i'm dealing with similar situation, we didn't expect weather to be as cold, so extra wood is on my mind as well. Everyone might need to go to bed earlier and cook food that cooks short time since we low on wood !'
Utterance: 'Yes, that's very true. I would be willing to give up water for more firewood.'
answer:

No
