"I never once saw them embrace.
I never once saw them hold hands,
I never once saw them a kiss, or hug, or use words or terms of endearment, or speak to one another with any warmth or tenderness.
Not once.
Not ever! "

So,how often did LHP ever see John and Patsy together? She was a maid/cleaning woman. John would have been at work, not at home when LHP was there.

Let the children of LHP and her husband come forward and say that they remember their parents: holding hands, kissing, hugging, using words or terms of endearment, and speaking to one another with warmth and tenderness.

Also, I think this has overtones of the Madam. Evidently the assumption is that couples who love one another will show (in front of others) lots of: holding hands, kissing, hugging, using words or terms of endearment, or almost always speak to one another a lot with warmth or tenderness.

I am trying to remember my parents' behavior on this aspect. They would not have passed muster according to these criteria. But my mother often told to me, while Dad was at work, of her love and thankfulness for my father. And my father defended my mother strongly the one time I challenged him about her hurtful (menopausal) behavior towards me. They worked as a team to provide for their children, morally, spiritually, economically, etc. Their love for each other was very evident because we, the children, could see their dedication to each other, working together, and especially for their children.
