You know....my DD used to be much more like this, and now she isn't. I don't know what that is about. I did used to find it just a little troubling, in that it somehow read a little ASD-ish to me, in line with the "little professor" speech they describe for Asperger's. Or it just sounded a little quirky/off.
She is more likely to use big words slightly inappropriately in writing now. But she doesn't do it in speech. I have wondered if it's intentional; probably. Her social awareness gets better all the time.
She has definitely lost some of her ASD flags over the years (for instance, as I've mentioned elsewhere, she's gotten much less literal). She's always been gray area; really a tricky one.
eta: ah, just noticed what HK wrote!
I also liked larger, more sophisticated vocabulary, and definitely chose to use a greater variety of words, particularly in my writing. I had learned by then that doing so VERBALLY really marked one as an oddball in the communication department.
Yes, I think DD has figured this out as well.
