"From the outside, we may look healed up," explains Samina Irshad, section head of the Middle School at the Army Public School in Pakistan's frontier city of Peshawar.
But don't be fooled by appearances.
Irshad continues: "Our internal wounds, they'll take time." In fact, she estimates, it will take years.
Who knows how long it takes to recover from a massacre that included the death of 132 students, mostly teenaged boys, and 12 of Irshad's colleagues, including the school principal?
