Allie: (narrating) Most people change kind of slowly. They're who they are, and then after a while, they're someone else. But some people know the exact moment where their lives changed. They saw the person they were going to marry or the look in their baby's eyes the first time he smiled. For some people, it's not the good things in life that made them change. It's something they've gone through that makes everything they look at from that moment on seem very different from how it had always been.
