NEW YORK (Reuters) - For years, Madeleine Smithberg has been at the forefront of American comedy as co-creator of "The Daily Show" and a talent coordinator for "Late Show with David Letterman."
That sense of humor was especially handy during the last few years. That is because Smithberg had to cope with not one, but two elderly parents in rapid decline.
"It's heartbreaking," says Smithberg, 56, who heads a production company in Los Angeles. "And yet it's invisible, because nobody talks about it."
