There is a long-standing myth in the gifted education community that gifted children should not be accelerated so they can "make friends their own age." Even educators who have had a considerable amount of experience with gifted children who have been accelerated successfully still believe children will only find playmates among those of their own chronological age.
I beg to differ. It's very common for gifted kids to play with older *and* younger friends, as well as friends of the opposite gender, even when the other kids would never dare. I've seen it in my children as well as myself. I've never had more than one or two friends who are the same chronological age as me. Still don't.
Friendships are based on mutual interests (social) and understanding (emotional), which have little to do with birth year. One of the signs of giftedness is a dry or adult sense of humor. Can you make deep and lasting friendships with kids who don't get your jokes? Or, worse yet, who only think bathroom humor is funny?
We've been grouping children into grades according to birth year for so long, the practice is no longer questioned, even though it makes about as much sense as grouping them into grades according to astrological sign. At least all the kids born under the same sign should have the same personality, right?
