PROBLEM: Context: 'Hi, I will need alot of water as I need it to stay alive.' 'I agree, with camping i feel there are many uncertainties. Finding clean water would be too difficult, best to take as much water as possible. ' 'I will also need some Firewood too to start a fire'
Utterance: 'I feel for firewood we dont need as much, as we are going to be camping, with that means, in my opinion, with branches and brush available, maybe we can take 2 fire woods, what do you think?'

SOLUTION: No

PROBLEM: Context: 'Hi friend. 🙂 I'm going camping in the woods near my grandparents cabin. I'm inviting some friends along for a little bit of fun too because they have a guest house and a great field for tents. Would you like to come too? '
Utterance: 'Oh that sounds awesome. I am actually going camping with my grandparents and my children. So I would love to have 2 firewoods for them. They get cold easily so I would like a little extra to make sure they can stay warm throughout the evening. 🙂'

SOLUTION: No

PROBLEM: Context: 'I am hoping to receive 2 packages of food so that way you also have 1. ' 'That sounds great to me. I'm hoping to get 2 firewood, 1 water, and 1 food out of the deal. I'm amicable to more discussion though.' 'This also sounds like a fair deal to me! I am happy that we have reached a compromise so quickly on the packages based on our needs! '
Utterance: 'Me as well! I'm glad we could come to such a comprimise.'

SOLUTION:
No
