In this post Theory Corner considers the question of nature versus nurture. Are we shaped by genetics or by culture and experience? I don't know the answer but I can relate a story I heard that might be helpful.
It begins with twins born in a peaceful little cottage, nestled in the hills.
Fortunately for her, the man who found her was the King of the Hillbillies. He treated her like mountain royalty but unfortunately he was fatally kicked by a mule and Mildred found herself on her own.
BTW: Thanks to the anonymous person who who grafted the two women together on the title card.
