Here's something I recommend: Find all the video clips you can of joint press coverage of Donald Trump and his guest Angela Merkel. Turn off the sound, and just watch their body language. It's so awkwardly painful to watch Trump's glum demeanor, his silently ignoring her suggestion that they do a handshake for the photographers, and his avoiding ever making any eye contact with her.
The best tweet I've seen about this so far is from @TeaPainUSA:
"Today we have a smart, level-headed and decisive leader in Washington, D.C. Too bad she has to go back to Germany."
