President Obama has recently returned from his trip from Latin America to find the door of the West Wing locked. The door was locked because apparently he had arrived in the White House earlier than expected. This was reported by international news sites, March 26, 2011.
He walked to the West Wing and opened the door but found it locked. Just like any sane person the President skirted the building calmly to find an open door.
That was a response expected from a president. There are some similar incidents in which the president responded in consternation and irritation. Bravo for President Obama!
