I knew the names of their wives and their children. I had stored up a large bank of favors. I cashed them all in-and then borrowed heavily-during the genocide. My preexisting friendship with General Augustin Bizimungu in particular helped save the Mille Collines from being raided many times over. But alliances always shift, particularly in the chaos of war, and I knew my supply of liquor and favors would run dry in some crucial quarters. Before the hundred days were over a squad of soldiers was dispatched to kill me. I survived only after a desperate half hour during which I called in even more favors.

All these things helped me during the genocide. But they don’t explain everything.

Let me tell you what I think was the most important thing of all.

I will never forget walking out of my house the first day of the killings. There were people in the streets who I had known for seven years, neighbors of mine who had come over to our place for our regular Sunday cookouts. These people were wearing military uniforms that had been handed out by the militia. They were holding machetes and were trying to get inside the houses of those they knew to be Tutsi, those who had Tutsi relatives, or those who refused to go along with the murders.

There was one man in particular whom I will call Peter, though that is not his real name. He was a truck driver, about thirty years old, with a young wife. The best word I can use to describe him is an American word: cool. Peter was just a cool guy; so nice to children, very gentle, kind of a kidder, but never mean with his humor. I saw him that morning wearing a military uniform and holding a machete dripping in blood. Watching this happen in my own neighborhood was like looking up at a blue summer sky and seeing it suddenly turning to purple. The entire world had gone mad around me.

What had caused this to happen? Very simple: words.
