From my new Time.com story:
Add to the logistical glitches the wide-eyed excitement of doing everything for the first time, and what you get are lots of unscripted moments. On Wednesday, when President Obama entered a briefing room at the Old Executive office building, his staff and the press instinctively stood up. Obama was taken off guard. “I’m still getting used to that,” he said, after telling everyone to have a seat. Later in the same event, Obama struggled with the practice of using a different pen for every document he signed. “They are very nice pens,” the President advised his aides.
Vice President Biden stood to his right, apparently unsure if he or Lisa Brown, the staff secretary, should pick up the documents as Obama finished. Biden handled a couple, and then decided he’d better not. “Why don’t you take the last one,” he told Brown, with a smile. A few moments later, Biden was caught by surprise when Obama asked him to swear in the senior staff. “Am I doing this again?” he asked, confused, having just sworn in the members of the cabinet in a private ceremony.
