"A man, a painter, telephoned me," said Sendler, "`I remember your face,' he said. `It was you who took me out of the ghetto.' I had many calls like that!"
Irena Sendler did not think of herself as a hero. She claimed no credit for her actions. "I could have done more," she said. "This regret will follow me to my death."
