If my first grader was reading Harry Potter I am guessing I would suspect giftedness, but if you had never even heard of giftedness then I guess it is a case of you don't know what you don't know.

People have always commented, always suggested, always said something about her so at the ripe young age of 6 I feel like this has been on my mind for a lifetime...I guess because it has!
I'm sure that I had heard of giftedness, but I guess that I imagined it to be much more rare than it is (like highly prominent individuals such as Einstein or Bill Gates and maybe one kid in my high school). I wasn't offended, btw

As far as people commenting, I don't recall that much with dd either, honestly. Partially it was b/c there is a lot of that type of stuff in the family so to speak and it isn't atypical amongst family members. The other part was that I had a very limited social circle of other moms when dds were young and the other few kids we knew, I just assumed were slowish plus there have been some weird competitive parent issues where the response to dds was not, "wow, my kid can't do that," but rather to insist that their kid is doing more when that isn't the case.
