I’m not OCD, though my friends/family will sometimes joke that I am. I hate mess, and I hate clutter. I spend 30 minutes making my bed because I want to make sure it looks neat, since it sits in the middle of the room, and it’s the first thing you see when you walk past my door. I admit it’s ridiculous, I’m just going to sleep in it and mess it up, but until I actually do sleep in it, I want it neat. All my books/CDs/DVDs/albums are in alphabetical order by artist (or author), as it makes it easier for me to find something right away instead of hunting for it. The clothes in my closet are hung up according to type, with dress pants, dress shirts, tank tops, and t-shirts going from left to right. Again, that makes it easier to find stuff.
Is any of that weird to you? I’m not so anal that I can’t abide crumbs on the table or a single hair on a counter, but in the main, I like things to be clean.
