Grocery shopping to humans is kind of like hunting but for animals . . . but easier, so much easier.
Basically everyone has to do it to survive unless you want to be an animal and hunt . . . my dad does that sometimes, i actually had deer the other night. BUT when my provider leaves town I have to fend for myself the only way i know how . . . Grocery Shopping. I pick the foods I feel like eating almost any food i want and then trade it for green paper. It's almost always done in a huge building with hundreds of other humans doing the same thing, but there's no competition because there's enough for everyone! It sounds crazy, i know, but it's just what we humans do.
