If it's my video games, manga, anime, AKA, things I actually care about, I'm definitely a neat freak. And you should see my Graphics Resources folder. <_< I've got it all sorted out, and even retitled the sub-sub-folders so that I know who to credit and such whenever I'm not lazy enough to keep track of the things I use.
But if it comes to my bedroom, I'm totally cluttered, other than that little spotless area where my manga books are housed. Seriously, I go back to my room after I'm dead tired. As if I want to clean it up. <_< But if I do go in there during the day, which is rare, then I will tend to pick things up, mostly because I'm extremely paranoid about bugs, and any place that a bug can hide is an enemy to me. <3
