I would really like 2 packages of firewood and 2 of food. But I can do with one package of water. 
Okay I can agree to 2 of the water.
I already don't drink much water so I can get away with 1. 🙂 I am worried about not having enough food because I am pregnant. 
I can give you all 3 of the food, if you can give me 2 of the firewood because I am going somewhere really cold and need the wood to make fires.
I would worry about you not having any food! I am always cold and feel like I will be freezing and lose to much body heat if I don't have enough firewood. 
I am not worried about food, I have plenty but I need at least two of the firewood for where I am going.
I'm not sure how to make that work. ☹️ I wonder if the extra food would help keep me warm?
You would still have one of the firewood but a good amount of food since you are pregnant. Perhaps you could bring warm soups or cocoa.
Yes, that might work! Maybe my extra fat will keep me warm! 😮
So we can do 3 food for you, 1 water, 1 firewood, and 0 food for myself, 2 water, and 2 firewood?
I would be happy with that if you think you will be okay with it! 🙂
Yes
Thank you so much. It has been a pleasure dealing with you. I hope you have a great trip!
