Context: 'I am here with my family and we love to eat fish.🙂  Maybe if you spend tonight sleeping in your car or camper I can keep the fire wood. In exchange I will give you the 2 additional food packages and all 3 of the water packages. It's only for 1 night.' 'Why would you want to give up all that water? You're going to need extra water for your family to drink. All the sodium in the fish is going to make you all thirsty!' 'Your right,😮  I didn't think about that. But will probably only need 1 extra package of water so, in exchange I will offer you 1 package of firewood.'
Utterance: 'I know this isn't your problem, but I'm a student and I had to come up here to take photos of the night sky for my astronomy class. I slept really late today as I have to sit up all night to get the different stars, and possibly even the space station if it's clear enough out. I have to sit by a fire to stay warm so I can get these pictures to hand in to my professor tomorrow.'
