What is my biggest pet peeve? Why? What lengths would you go in order to avoid it?

Ever since i have worked at my job "Plants and Things" i have always been a organized neat person. When i worked there we would have to move statues, sheds, furniture, etc, and when we moved these items we would have to have everything in nice, neat, well balanced rows. Everything had to look good, for the customer and my boss. Since working there i now do this with everything in everyday life. For example when i go grocery shopping i would bring home all the food and i would make it well organized in my fridge. I would make sure everything is in plain view and that things are close to the front and in straight lines. I really cant avoid it because i get great satisfaction out of it when it looks all nice and tidy. I enjoy it when i do this because i like to be a neat, clean, tidy person.
