Order is never observed it is disorder that attracts attention because it is awkward and intrusive
Disorder means the exact opposite of order, and it can refer to a certain state or a medical condition. If you are diagnosed with Diabetes then you have a disorder that requires treatment. If your room is in a state of disorder then it is not clean or organized, instead chaos will rule and your items may be thrown about haphazardly. This can lead to difficulty finding anything that you are looking for.
