Pope recalls 'joy,' difficulties in final audience

A sign with writing in French reading "Thank you" is seen in the crowd attending Pope Benedict XVI's last general audience, at the Vatican, Wednesday, Feb. 27, 2013. Benedict XVI basked in an emotional sendoff Wednesday at his final general audience in St. Peter's Square, recalling moments of "joy and light" during his papacy but also times of great difficulty. He also thanked his flock for respecting his decision to retire. (AP Photo/Andrew Medichini)
