I have majjjjjjor OCD so I have a lot of these weird habits....a few are:
*My room MUST BE CLEAN AT ALL times!!! If there is ANYTHING, I mean a tiny shred of paper, and I'll get like short of breath until it's thrown away.
*All my DVD's are alphabetized as well as my CD's
*My bed MUST be made before I sleep in it, if it isn't made when I'm going to bed, I'll make it and then unmake it to sleep in it.
*When I am playing cards and the cards don't have to be in any order, I have to put them in order, from lowest to highest. And all the red cards must be first, black cards second. And I order them from hearts, spades, diamonds, and then clubs.
*All my lightswitches in my parents house MUST BE TURNED THE SAME WAY!!! We have some rooms where you can turn the lights on and off with more than one switch, uggghh that drives me nuts!!!
*My closet is organized by color and style of clothing, I freak out if it's not the right wasy. My tshirts must also be folded in the exact same way everytime or else it really bothers me.
*I will NEVER leave my house without makeup, just won't ever happen.
*I can not eat my food unless it is all mixed up together, I don't like to eat any of my foods separate, I mush everything in to a big mess, or else I can't eat it. my parents hate this!
*My handwriting must always be in all print or all cursive....if I switch in the middle of the page, I'll throw that page away and start over.
*When I set my alarm the time I wake up always has to end with a 3....like 12:03, 12:13, 12:23, 12:33, etc. you know? Otherwise it reallllllly bothers me!
I am a huge perfectionist, so all this stuff which might seem stupid to other people, really drives me crazy if it isn't the way I need it to be. Hahah, needless to say I am constantly cleaning and I annoy a lot of people with these weird habits. These are just a few of mine, I know I have lots lots more!
