I have two kids who answer "nothing" when asked what they did at school today. One is HG+ and grade skipped and thriving, the other is MG but seriously 2E and doesn't remotely look gifted at school. They just don't seem to be either interested in retelling, or able to figure out what to retell about their days. My 3yr old is now better at recounting her day than the grade 2 or grade 6 child... I know other folks with HG+ kids who give them excruciating details about every minute of the day until the parents' ears are bleeding... I don't know that this is about giftedness so much as personality...
