[Q]: Context: 'I was hoping for a decent amount of food, just in case my new recipes don't work out, lol. 🙂' 'Haha, makes sense. I'm also interested in food. What if I take 2 waters and 1 food, and you take 1 water and 2 food?' 'I would be okay with that if I could also have all of the firewood. It seems fair since you will be getting the most water.
