A bit from a soldier:
"The experience of war changes people. For some it is a negative change but most manage to absorb the experience and use it to make themselves stronger. I have said goodbye to a mortally wounded soldier in the hospital, spoken to grieving family members of our casualties, and tried to comfort soldiers who just lost their best friend in a single violent moment. I have been under fire, looked insurgents in the eye, and seen corruption up close. I have also seen people emerge from oppression and live with hope for the first time in years. I have seen children reach up and grasp the hands of American soldiers just because they trust them. I have felt the desire to help and then been given the resources to do it. Finally, I have felt the close knit camaraderie that develops when you serve with a group of people fighting for a cause larger than self. Yes, this experience has changed me. I am stronger, more driven, and humbled all at the same time."
That's a nice outline. Read the whole thing. The part about the man's shop is truly touching.
