Hi.  I am looking at possibly taking 3 of the food packages, 2 of the water packages and one of the firewood.  
Hi. Why do you need so many food packages?
Well, I have two teenage boys who will be with me.  In normal circumstances they go through a lot of food.  While camping, hiking and kayaking I know we will need plenty to keep their energy level high to do everything.🙂
Well I will definitely need 2 packages of food and 2 of firewood for survival.
I am definitely ok with giving you two of the firewood!!  Why do you need 2 packages of food?
I have a very fast metabolism and a dog to take care of. Thanks for the firewood.
Awe!  We have a dog as well, I love dogs!!  How about if you get 1 package of food, 1 water and 2 firewood?  Would that be sufficient for you?
I know I will need at least 2 packages of food. But you can have 2 of water.
I'm so sorry, we're getting very close to the end and will need to make a decision very soon!  We can go without any firewood so How about you get all 2 firewood, 2 water and 1 food.  I will really need at least 2 packages of food for all of us.
That works for me
