Why was Susan Dell turning her head in such a weird way

Why was Susan Dell turning her head in such a weird way? She even patted Trump on the shoulder like she was the one in charge. At the White House event, Susan Dell, philanthropist and wife of Michael Dell, CEO of Dell Technologies, delivered a speech encouraging people to sign up for Trump's child accounts. But what really caught people's attention wasn't her speech, it was her unusual body language and facial expressions. First, she kept the same stiff, almost 45-degree smile throughout the entire event, and with her sunken eyes and heavy smoky eye makeup, looked larger reminiscent of the doll Annabelle. Even eerier, there's a strange bulge in the middle of her neck that moves up and down as she speaks, and it wasn't visible in her earlier videos. Secondly, she keeps her arms hanging straight down without shifting her posture at all. Her shoulders are hunched high and her head tilts constantly to the left, as if bearing a heavy weight, unable to remain upright. This is clearly not something an ordinary person can sustain. Third, her speech during the address is incredibly steady and devoid of any accent. Her entire performance felt more like a robot than a real person. Everyone thinks something's off. Hopefully, it's just too much plastic surgery and nothing more serious.
