One truly bizarre experience that my DD has run into is that the BETTER she seems to handle herself, (that is, the less "child-like" and irrational/unpredictable/emotional she is), the more she seems to wind some adults up.
Not sure how to coach her out of that one.
Here, honey-- study your agemates, and let's role play how a typical 16yo girl would handle being called into the dean's office (just an example).
Here's how a typical 15yo would respond when a TSA agent tells them to do something that isn't technically required by law...
That's the kind of thing that I'm getting at. Spaghetti's advice is very very good in situations like that-- the child HAS to remind the adult somehow that in spite of their gut instincts, they ARE still dealing with a person who is very much a child.
