I'm assuming this is "GM3
things you are very picky about". You left out a word

.
My desk. The papers must be lined up and in order. I like all the pencils sharpened to the same point, and don't like one stubby little pencil amongst the tall ones. The stapler, the tape, the paper clip tray must be lined up, and the tray must have the correct number of clips in it. I wish my OCD would extend to the rest of my house and car, not just work :P.
Laundry soap, but that's because of sensitive skin.
Food. Not so much what I'm eating, but how. I eat in a particular order. I also don't like food to touch on the plate (except something like Chinese, all mixed up).
GM3 out of place items you can see from where you are sitting.
