Not too sure why this has suddenly been getting a lot of attention, but back in 2019 the Duchess of Sussex (Meghan Markle) attended the US Open Final which her friend Serena Williams was playing in. Meghan was seated directly next to Oracene Price, the mother of Serena Williams.
During the match, Meghan makes multiple efforts to try to capture Oracene's attention, but these attempts are either unnoticed or ignored by Oracene. A body language expert comments in the article that, upon realising the cameras are on her, Meghan performs a series of "theatrical movements" in an attempt to defuse the awkwardness of the situation. The body language expert also reports that Oracene's behaviour could be construed as a sign of pre-existing tension between her and Meghan. She goes into a lot more detail in the article itself, which I thought was fascinating. The link is below.
