That was another story I was going to highlight, yggdrasil. There is another, and a just as plausible interpretation of that quick change of expression on Melania's face. Trump turned and spoke to her during a service. She smiled in response and then realised that another prayer had begun and resumed what observers are calling her "prayer face" immediately, as one would. She also bowed her head slightly. Again, as one would at prayer time.
Much as I am as dubious about Trump's good qualities as everyone else, the prayer face interpretation strikes me as much more believable than Melania hating her husband. Plus, the negative interpretations, as the example above shows, are often taken out of context. Context matters.
