It is estimated 2-3% of the population has some form of OCD, so I'm sure you will meet someone with the condition at some point! And yes, it does annoy me when people say they're 'a bit OCD' because they are an organised person or a clean freak. I don't think they understand how devestating the condition can be for people- it's much more than having all of your felt tips colours in order! Saying this, I don't think i've ever pulled someone up on saying 'they're a bit OCD', mostly because they would wonder what my authority was saying that. 'How would you know?' This is because apart from my close friends, I don't tell people I have the condition, as then i'd have to explain what I obsess over.
