"mant gifted people energized by being alone. This is called introversion. While they may like being around other people, it drains their energy reserves. They seek opportunities to recharge by being alone or escaping into a good book."
This exactly describes my hu*****and and his mother. But we don't know if they are gifted, but my mother-in law did skip a grade when she was in school.
Our daughter is gifted with IQ140, but she is very extrovert. and then of course she has play dates all the time and she knows she is loved and cute. She has tantrums when she is tired, very bad ones. she is almost 5 now, things got a lot better.
And from my side, my mother is very"naotong" in her whole life.
