Security Grapefruit

There's this huge juicy grapefruit I put into my bag 2 days ago. I love the smell and I've been meaning to eat it, but I am too lazy to peel it because it gets so messy. I will eat it soon, that's what I always say. But it's more like a security grapefruit.. so if the world has a sudden WW3, I can hide in a nuclear safe area and eat my grapefruit piece by piece.
