Hi, Bluespiral!
I know that my messiness is derived from someone, at least once, having tried to make me be neater.
Reactive, oh yes. That would be me!
It was enough to throw me the other way for at least the rest of THIS lifetime! Not the kind of thing a MATURE person would do, or so I understand from reading about that "maturity" thing.
But I do have some neat traits, which I call OCD or O. Seed D. Of course they go to the extreme opposite!
Enantiodromia, I hope they never invent a pill for it! If you can't enjoy a thing AND its opposite, what CAN you enjoy?
