Seriously, we had almost my whole family together recently, & what did Spouse remark to me about that he thought made this Niece different to my siblings other kids? Self-awareness. He said he was impressed that a child at her age had such a clear idea of who she was & how she wanted to be.
He looked at my other niblings & saw a bunch of sweet kids, but it was this particular child he noticed & said "THAT one knows who she is."
