When Dad was gone, my mom was a totally different woman. Don’t get me wrong. Whether he was home or not, she was always smiling. It was how I learned what an incredible disguise a grin could be. People didn’t pry about why you had bruises if you were happy. Nor did they inquire if there was enough food to feed your children or if your husband had spent all of his money on beer, video poker, and truck-stop hookers. (Yeah, my old man was a real class act.) People didn’t actually ask questions at all if you were sporting a smile. It became my family’s greatest defense.
