So, you want some code, eh? Here is some code for you. Hopefully this logic will help you understand that fiction (and fake things) (I will describe that second.) are indeed real.

1 using nonexistent as the opposite of real;
2 Item_X = anything;
3 if(Item_X exists in the world of nonfiction && Item_X does not exist in the world of fiction)
4 Item_X is real.;
5 elseif(Item_X exists in the world of fiction && Item_X does not exist in the world of nonfiction)
6 Item_X is real.; //I think that this can be considered "Confusion: Part 1 of 2" for most people.
7 elseif(Item_X exists in the world of fiction && Item_X exists in the world of nonfiction)
8 Item_X is real.; //I think that this can be considered "Confusion: Part 2 of 2" for most people.
9 else
10 Item_X does not exist in either world and thus is not real.;

Now for the term fake:
I think of this as a synonym for false. A common example is fake fruit. Using the logic above, it is real due to its existence. It is fake, however, because it supplies no sustenance (because it is generally made of plastic, which does not supply sustenance that I am aware of).
