I've seen this quote before and I think it's silly because that makes it Compulsive Disorder Obsessive and that doesn't make any sence. It's Obsessive Compulsive Disorder, and even that doesn't properly explain the condition. It should be called Scary Intrusive Thoughts Disorder or something like that.
Isn't it annoying that you can pretty much never walk into a store where it's all alphabetised? I have other little quirks too but that's my hardest to deal with. Volunteering in a shop doesn't help. XD
