Hey, nice getting to interact with you. 
Hi there! its really nice to meet you. 
So, let's get to discuss on our camping trip. I prefer having additional packages of food. your thoughts?
I would also prefer the additional packages of food. I have diabetes and if my blood sugar drops to low it will cause me to have a wide variety of health issues we would need to deal with. 
I understand, in that case I can substitute with water. So, can I have 1 and 2 packages of food and water each.
Yes, I agree to that deal. How about firewood? I can I have one of your packages of firewood as I will have additional food to cook?
Yes, that would do, you can have 2 of it as you have additional food. I would do with 1 of food, 1 of firewood and 2 of water. Let me know if you have any concerns.
That works for me! Thanks! 
Thanks, it was really nice talking to you. Take care
Have a great rest of your day! See you out in the wild 🙂
