I have really strange OCD because i'm actually a very messy, unorganised person, but there's certain things that I just have to do or they'll drive me insane. Like I can't stand it when someone has the label of their shirt hanging out, to the extent that if it's a stranger on the street, I'll tell them to tuck it in. And I can't stand it when the microwave door is open. And the volume on my radio has to be set at multiples of 5, but on my TV it has to be odd numbers except for 4, 12, 36 because they're square numbers. And my CDs have to be in alphabetical order.
