Gwen: Then why?
John: There’s no will to do it, and that’s because there’s no understanding.... I often think, now, of being in the trenches.

Gwen: The friends you made....
John: No. The strangers on the road, day and night, at the same task; one’s rest and play only to give one strength for it; a purpose that gave meaning to every moment.
