Mach & Starsky remind me about my own late, beloved father.
When I was a youngster (read 2 years old), my mother had already married her OM and somehow she started me in on calling him "Daddy." When my father learned of this, he FLIPPED out and went right up to my mother's front door. Then and right there, he told her in no uncertain terms that he's my ONE and ONLY father and he's the only person I am to call "Daddy." That put a stop to calling the OM "Daddy" pretty quickly. From there and on I called him by his name.
My Dad wasn't one for taking chit and stood up for himself (and for ME too). My hero despite his propensity for gazillions OWs. eye-rolling Dad may have had his own failings as a man, but was an A+ as a father in my mind & eyes.
