I think the one I find most annoying is when someone describes any of my kids as "freakishly smart". A compliment and insult all in one.

I have found that other parents, strangers and kids are much more comfortable with the extreme talents with my 2e son than they were with my high gifted son who was gifted in all exceptionalities tested. Seems human nature is more willing to embrace superiority when it is also served up with struggle in something else. It's ok to be able to recite from memory, including side effects, complete audio books at the age of three if that same child has a speech disorder.
