Quote from Sushiirull
:B I thought so too. But my rooms is such a mess, and I don't even really care. Except that I have 5 things on my bed, and I would rather have 9. That means I could add 4 things, and that makes me happy. Or I could remove 1 thing to leave 4 things on my bed, but I would have to remove 1 thing. That means that option 2 would leave me having to use 2 numbers: 1 and 5. But since It's option 2 and there are 2 bad numbers, I can add that to 4, so that would be okay.
Obsessive-compulsive doesn't have to have obsessions and compulsions, it's still OCD just with compulsions only.
