There was a moment during Michelle Obama's speech at the Democratic National Convention last Tuesday night when I thought someone had heckled the First Lady right to her face on international television.

She was talking about who the president is, how the presidency hasn’t changed him, and some of the things he fills his personal time with.

“He’s the same man who started his career by turning down high-paying jobs,” she said, a deep blue screen in the background, huge white stars behind her back and over her left shoulder. “That’s the man I see in those quiet moments, late at night, hunched over his desk, poring over the letters people have sent him.”

And that’s when it happened.
