I have no idea about Ms Angela Merkel in person, in private but her grace, poise, tact and diplomacy has gone totally unnoticed in the embarrassing (to the USofA) reception by the President. Even her body language seemed to invite civility of encounter.  Unmet by Trump. Her early acknowledgement of Trump's nasty "tweets" by indicating how much better it is to "talk to" rather than "talk about", leaves no question about her awareness of and what she thought of, how she was pilloried by candidate Trump. And yet she was graceful.
Good on you Chancellor Merkel!
