this was 100% a coincidence, I'm sure, but my crazy math-head son, 3yo, was at McDonalds with his dad and brother...and he was playing with a little girl that he just met (she was maybe 6 or something?) Anyway, she came over to my husband and said 'your son is really smart', and DH said, "what did he do?" and she said, 'he guessed my lucky number!' (it was 16). he was just like, 'oh??'. telepathy is totally a giftedness trait, right? wink
