My role in society or any artist's or poet's role is to try and express what we all feel. Not to tell people how to feel. Not as a preacher not as a leader but as a reflection of us all.
My dad served in the Air Force as ground crew for several years and doesn't really talk about it. I know that it's there. I think my main thing about direct or indirect experiences as near to home as it were is the idea of self-sacrifice really.
