Firstborn, only girl.
.....My father wanted all sons, to help on the farm...
Brother, 2 years younger
Brother, 5 years younger than that one
Brother, 2 years after that one.
So, since I was oldest, and a disappointing girl-child, I had to not only try to be the boy my father wanted, but the babysitter of my brothers, from the time I could walk.
Mom's nickname for me is O&O: Oldest & Only
