"People need depth, and depth means the possibility of unhappiness and frustration and sometimes torment — though hopefully not madness." -- Oliver Sacks

We've all had that moment. The moment where you might see or hear something and you wonder: Am I going crazy? In this hour, TED speakers share their experiences straddling that line between madness and sanity — and question if we're all in the gray area between the two.

My father, sister and I sat in the near-empty Chinese restaurant, picking at our plates, unable to avoid the question that we'd gathered to discuss: When was it time to let Mom die?

On a day when we're in the final countdown for sequestration, Washington is still abuzz over whether or not White House economic adviser Gene Sperling threatened journalist Bob Woodward.

The sequester is upon us, and NPR's Ken Rudin and Ron Elving try to explain how it all affects them. But it's a good week for Chuck Hagel, who finally gets the votes he needs to become Defense Secretary, and Robin Kelly, who wins the Democratic primary in Illinois' 2nd district and is likely to succeed Jesse Jackson Jr. in the House.

The technical director speaks as if the lights were some living being. We haven't progressed far enough with our lighting system that we can control it.

Republican Party Chairman Reince Priebus has begun a series of meetings with groups that have overwhelmingly gone Democratic in the past two presidential elections.

He's sitting down with Latino and Asian voters and with young people across the country. The youth group is of particular concern to the GOP because voting habits established at this stage could last a lifetime.

College students at Ohio State University were eager to talk about the state of the GOP brand. The class is called American Political Parties.

STEVE INSKEEP, HOST:

And I'm Steve Inskeep. Good morning. In Italy the papacy is officially vacant. The Vatican is now under the control of the cardinals who will elect a new leader of the Catholic Church. Yesterday Pope Benedict XVI gave up his ring, his cape and red papal shoes to become Pope Emeritus. Cokie Roberts was there, joins us from Rome. Hi, Cokie.
