I think the worst kind of tags I got in that post with the stupid Tolkien and CS Lewis tags (you know the one) was those that implied that Tolkien used the concept of LOTR being a fictional translation to "avoid" explaining things. First of all, as if Tolkien would use any excuse to be lazy about WRITING of all things, he was using it to make his story feel more real, more rich, he was trying to build myth and he knew how to do it in a way few people could.. Segundo, Francia, and third, that's called narrative framing, it's been used since ancient times and it's something I don't even feel qualified to even talk about because I'm sure people have written entire papers on it.
Just the idea of Tolkien being lazy. Goddamn.
