Clean... clean... everything must be clean
Obessesive compulsive disorder emits a bad connnotation to the masses, but to the person living with OCD, It can be both a blessing and a curse.

I can't stand mess, I double- no, triple check things before I do somthing. It's a huge timesink, yet at the same time it ensures that what I'm doing at the time will be right. The constant fear of doing somthing wrong can be sometimes unbearable.

These are the kind of people who assess every possible outcome before they act, these are the people who stand in line in front of a mc donalds and dont decide what to get until they're ready to be served, these are the people who will constantly check and recheck if they've turned off the stove before they left because of the fear of burning their house down.

These are the people living with OCD.

For anyone else, these people can be a pain to deal with as they'll refuse to proceed until they're one hundred percent certain that they've chosen the correct course of action. It's simple, really: they ignore nothing, yet overestemate everything.
