It was a very serious Josh who stood before the group of students and tried not to think too much on the one face that should still be there.
"Welcome to the White House," he said. "We have been granted a very special privilege--they're letting us walk around while the President is still in the Oval Office." He made eye contact with each student. "If any of you do anything to embarrass me or the school, a year's worth of detention will be the least of your problems. The President's Secret Service detail qualifies with their weapons once a month and they don't miss unless they want to."
He handed out their visitor passes. "I have a couple of people I need to talk to while I'm here, but the staff knows you're with me, so feel free to wander just a little bit around the West Wing. If you go anywhere near a place where the walls start curving out, turn around and go back the way you came. We'll meet the President before we go, but you aren't going to randomly stumble into his office and set off World War III."
