Hello, how are you?
I am doing well. How are you? \
Doing ok. Just gathering all the stuff we need for the camping trip this weekend. It's going to be my kids' first so they're looking foward to it.
I'm so happy to hear that they are looking forward to a good time. I am also looking forward to the trip with my family. I would like to have additional food and water packages to make our trip better. What are the things that you would like more of? 
Unfortunately I also need food and water as well. My kids are diabetic so they need to have a stable amount of food and water for their medications.
How about I provide you with 2 packs of water and I will take 1. For the food maybe I can have 2 and you can have one? 
They need food more than water to keep their levels constant. I am willing to offer 2 packs of water, 1 food and 2 firewood?
Sounds good to me. 
ok appreciate your understanding. I'll be able to send over a proposal shortly
Okay, I hope that your kids stay healthy and happy during your trip.
