Queen Elizabeth II may not have been amused, but the Twitterati certainly were.

During President Trump’s hourlong visit with the queen at Windsor Castle on Friday — they shared tea, a handshake and traditional pomp-and-circumstance — one awkward moment stood out on social media. It was when President Trump momentarily seemed to (gasp!) walk in front of the queen.

Mr. Trump walked slightly ahead of the queen as they inspected her honor guard. At one point, she gestured to Mr. Trump and appeared to direct him forward with her white-gloved right hand. He walked in front of her and then stopped, which cut off her path and forced her to sidestep around him.
