Knowing a family friend's daughter like this, I do hope this child receives support from her family to ward off any problems, possibly including a reliable therapist. When such children are young, they can indeed sort things out and make order of their rooms, their family pantry or linen closet, the toy room, etc. But as they grow and start to experience the often disorderly way most other individuals and institutions operate, their frustration levels rise and sometimes result in anger outbursts or being known as "crazy", "anal", stubborn or troublesome in school or at work.
The other issue is that the transgender movement is making an effort to "recruit" Asperger kids. Of course, they are putting out a bunch of b.s. "literature" to support their claims that this is an inevitable link. So the choice of a reliable counselor must screen out the danger of indoctrination on this issue.
You may have missed the part where I explained that she is 9 years old now and perfectly fine.
