Disorganized is a broad term.
I often leave used clothes, lying around in my apartement. Then again, I live alone and am a grown up person. If the clothes bother me, I will remove them. If not, they will stay on the floor, till laundry day. I don't have a mother or a partner, waging their finger at me.
On the other hand, I am never late and never miss out on any duties that actually matter, like dates for exams.
So am I disorganized?
There is a difference between gross neglegance of orginization and simply not bother with things that other fancy important.
