Karen, I agree with so much of this! Indeed, we focus so much on classroom management or the adult world equivalents — population mngt, perhaps? — that we lose track of outliers and individuality. Children and adults are judged based on their ability to conform and harshly derided when they cannot (not will not, but cannot). Drives me nuts!
Caveat: I think that acknowledging that giftedness can be a curse as much as a blessing is intended to point out that giftedness is not all rainbows and unicorns — which is true, awkward working notwithstanding. There is definitely a challenging side, although I would never use the word “suffering” to describe it.
