A striking photograph of Donald Trump, Melania Trump and Chinese President Xi Jinping has sparked intense online reactions. Body-language expert Sean Johns says Trump’s compressed lips, jaw tension and posture appear to suggest what he describes as “controlled anger,” while he says Melania appears “concerned.” Social media users had their own dramatic interpretations, with some calling the image “chilling” and even comparing it to a horror-movie poster. But body language cannot establish what the three leaders were actually thinking or feeling in that moment.
