I am the planned bastard son of two people, my Mom and Dad of course. My mother was a middle child of 4. Of her siblings two are deaf and dumb (can't hear or speak), her older brother and herself though we're as perfectly normal as any others at the time. Born in a small town in western Pennsylvania, her father, a navy veteran, golden gloves boxer, and submariner. Her mother, had chosen to work rather than be a housewife, she was a switch operator for the local Bell telephone company, along with other professions along the way, but I can't recall the others. My mother, and her oldest brother, not having any issues with communication, would be tasked with looking over the other two, and would be the "go to" children when tasks needed done. Physical work tasked to the oldest brother, and housework tasked to my mother. That's just how it was back then, and now the sculpting it had on the personalities of each of them are easily recognized.
That's my Mom's origins.
