Remember the feature film, The Butler, with
Forrest Whittaker as the White House chief butler who lived
to greet President Obama as a guest and not as an employee.

I remember that final scene and final line,
when said butler (recently widowed, the wife played by Oprah Winfrey)
came to the White House to receive an honor from the President.
The new butler started to direct the old man towards
the function room in question,
and with dignity, the former butler said:
"I know the way." And walked to the President, alone.

With the transition between new Presidents and new Administrations,
a former Obama speechwriter, who continued to cover stories as a journalist after Obama left office,
authored "The Secret Life of the White House" for a feature story
in the New Yorker.
