Freeze-dried food without adding boiled water sounds nasty! Google says cold water will do the trick with more time, but I'm skeptical haha. I don't know these characters' personalities, but I bet the practical one is more optimistic about it ("Just has a little crunch is all") whereas the other one is disgusted ("A little crunch?

John 14:27 Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid.
You have to write the book that wants to be written. And if the book will be too difficult for grown-ups, then you write it for children. — Madeleine L'Engle, Author
