It's awfully real when you are hungry.

You can't eat money, it doesn't grow on trees. Well, I guess you can eat it but it has no nutritional value.

There are a lot of things you can’t eat, but are very important tools to help you get food. Words, ideas, friendships, jobs. None of them are edible, but very useful. Money is another one.

So is sanity :-P
