Miel,
I've checked your profile page to find your home country , as there isn't one I'm going to assume you live in the US . From reading comments and threads from other members there is more of a difference between the various countries than I expected , issues in the US don't often figure in the UK . Saying that everyone is differnt anyway , as a GG you obviously don't like the female sterotype whereas others still totally embrace it .
On a personal level my sister was the apple of my father's eye when she was a child so she got most of the attention and I received most of the abuse , she could wear anything she chose and I had to be the rough , tough little boy whether I liked it or not .
My children received equal support , one was never favoured over the other , a boy and girl bring different aspects into family life both which proved enjoyable , both also received equal support through university and after the same support when buying and setting up homes when they married .
My son is now a qualifed structural engineer and my daughter a qualified nurse and speech and language therapist , both chose those subjects of their own free will .
