I know really young girls have a natural inclination to take care of things without any "training" and develop role playing later on to take care of people from watching others, family, teachers, role models to them. Not everyone develops this nuturing aspect though depending on what they see.

What struck me most about this passage, though provoking and not how things are supposed to be, was how very true it is for my grandmother and mother's generation. They were taught that their roles were to support and care for their husbands so they could succeed at whatever, sacrificing themselves in the process. Growing up, I saw my Mom and Dad slightly break away from my grandparents mold and were mutually supportive and caring (until recently as Mom battles with depression.) My grandmother was adamant I not do as she did, giving up all of herself to care for her husband saying how she missed out in life; it was unhealthy and how somewhat resentful she found herself at times as did her friends. Mutually caring and supportive is important. I tend see more nurturing in women however overall, a more natural inclination.
