I met xN's mother once. It was all I needed to be fairly certain that she's an N too....maybe a P. She had the coldest expression and the most vacant eyes. And she sat there like Zeus on the mountain, not speaking a word, as if everyone was completely beneath her. She once denied the xN as her son because she was dating a man who didn't want any children. Not making excuses for the xN's reprehensible behavior, but I can't imagine what it would be like to hear your own mother tell someone right in front of you that she doesn't have any children.
