I came upon an old man squatting beside a drainage ditch. He looked up as I approached, then leapt to his feet and brandished a rusty looking revolver.
“American! VC tell me, kill you. But I no can do this. My heart say no. My family have saying: ‘One man die, one man live’.”
And he turned the weapon upon himself and fired a bullet into his chest.
I’ll never understand why he did it, but I shall always remember his sacrifice.
