As I stepped down onto the tarmac at Quaid-e-Azam International Airport in Karachi on October 18, 2007, I was overcome with emotion. Like most women in politics, I am especially sensitive to maintaining my composure, to never showing my feelings. A display of emotion by a woman in politics or government can be misconstrued as a manifestation of weakness, reinforcing stereotypes and caricatures. But as my foot touched the ground of my beloved Pakistan for the first time after eight lonely and difficult years of exile, I could not stop the tears from pouring from my eyes and I lifted my hands in reverence, in thanks, and in prayer. I stood on the soil of Pakistan in awe. I felt that a huge burden, a terrible weight, had been lifted from my shoulders. It was a sense of liberation. I was home at long last. I knew why. I knew what I had to do.
