Wow, Tiz, your DS6 seems like my DS6.  Who is easily more than 2 years ahead of his agemates...but immature and SO SENSITIVE!
I am trying to work with our school to get him to show that he can do the work (he is pretty lazy when it comes to writing and.. 
http://giftedissues.davidsongifted.org/BB/ubbthreads.php/topics/36175/1) and then hopefully get something less dull to do.  We can't address the GT until they decide he isn't a behavior / LD problem. ugh.
Some day they'll want something - it will be hard - and they won't know how to meet a challenge.
I am also GT, and I remember how school was this place that I had to go everyday just because (except a few years in TX where the whole schools were ability differentiated into 12 bins!).  I never needed to look at anything more than once or study or do homework at home...yadda yadda.  And now, I wonder why I don't ever want to do anything that isn't super easy.  This (and his potentially wasted ability) is my biggest fear for DS6.
