Context: 'I enjoy camping as well. However, my campsite seems to be a bit chilly at night. I'd be willing to part with some firewood, yet I'd need quite a bit of food to compensate. I also have a stream nearby so water is plentiful if you need that as well.' 'I may be able to do something with regards to food. Do you have enough water?' 'I have more water than I need. How is your water supply?'
Utterance: 'I could use some more water as I get dehydrated easily. Since you have enough, I could give you and extra package of food for your water.'
