I'm kinda sick of people thinking OCD means "I am mildly bothered by these things not lining up right". Try living with someone who gets into hysterics if they can't wash their hands every 5 minutes, checks the laundry 7 times to see if they added detergent, freaks out if a dish might have a trace of washing up liquid left on it from not being rinsed correctly and redoes the entire stack of dishes just in case. (Ed: Not really a specific dig against this post, just a vaguely related ramble)
