Audrey Hepburn had tea with first lady Barbara Bush Friday after speaking at the National Press Club in Washington in her role as UNICEF goodwill ambassador. "There is unhappiness and need for greater advocacy for today's children, children haunted by malnutrition, disease and death," Hepburn said. "Less than half of 1 percent of today's world economy would be the total required to eradicate the worst aspects of poverty and would meet basic human needs over the next 10 years."
