My Mother and my wife both were "call girls" and then became "hookers"! Both spent many years as telephone operators. My Mother was operator in our small town. Folks would call her and say, "Don't ring me for an hour. I'm gonna go take a bath." When I met my wife, she was a telephone operator for Southwestern Bell. i.e. "Call girls". My Mother taught my wife how to crochet. When my Mother was near the end with her cancer, she could still sit upright and crochet. My wife's hands are getting quite arthritic, but she still crochets some... i.e. crochet hooks/"hookers".
