im saying people who always write clean as opposed to a dirty style, it says something about your personality, but this is over a long period large scale.
If a clean writer writes dirty ne night maybe they were a lil intoxicated or under more pressure or what have you.
If you paint a self portrait of yourself in a dirty manner as opposed to a clean representation either you view yourself as dirty, your under alot of stress or you are a dirty person.
If you paint it in a clean manner you either see yourself in a pure manner, you are clean and elegant or you are very anal about details.
i understand reputable psychologists put it down but maybe its not so much who you are before you wrote the message but more so of who you will be after you write the message.
