[Q]: Context: 'Ooh rock climbing! I'm definitely scared of heights, so that's out for me. I'm heading to the Puget Sound to camp near the ocean.' 'My wife is from the puget sound. Was just up there a month ago.  I am looking to take the food and water.  We have a large group and will be active.  We will have some hot and dry conditions in the desert. Some are high school age students with big appetites.  What are your preferences.' 'I was definitely looking to have food and firewood most of all. There are plenty of places to collect rainwater and get fresh water in Puget Sound, but we're lacking in food and will need firewood to start a campfire at night.'
Utterance: '😮 I see.  I am wiling to give you the firewood, but I also really need the food.  I could take the waters and two food, and how about if you take the firewood and 1 food? The firewood would be helpful since we need to cook a lot of our food and there is not much to collect in the desert, but if we can take extra food, then it will help solve that problem.🙂'

That gives you 1 food package and 2 waters and 3 firewoods.' 'I too have children who eat like adults they too can't able to withstand hunger so you please show some mercy and give me 3 food packages and take all water and firewood'
Utterance: 'No I need extra food too. I cannot let my children starve and you cant let your children go thirsty. So if you cant agree to share the food i will walk away from the deal.'
