I wasn't so anal before but once I became a homeowner there's countless things I'm anal about in my house.
If it's something I always do in my house I get extremely frustrated if anyone does it because they won't do it the way I do. Bigger things like the organization of my garage to small things like doing the dishes. In general, in every room I know where everything is because I put everything where it goes, if someone tries helping but does it differently they haven't helped me at all. My mom and my mother in law put dishes away where they don't go and then it becomes a big search to find them because even they don't remember where they put them.
At work, my desk seems like a mess but it's my mess, it looks a certain way to everyone else but I know where everything is and why it's there. Our computer tech is ridiculously OCD and she couldn't help herself one day and organized my fucking desk to her liking, my God I wanted to kill her. Don't touch my space.
