Every time we come to Rwanda, we take the students to visit some of the Genocide memorial sites to learn about the history. At Nyamata there is a church where 10,000 people were killed in and around the church in 1994. Inside the church they left piles and piles of clothes of the dead. In an underground chamber you walk through aisles the width of your shoulder, while on both sides are shelves and shelves of skulls and bones of the dead, so that everywhere you turn, the skulls are less than 2 feet from your face.
It is an extremely disturbing experience. But I force myself to go through the experience every time, to remind myself how evil we humans can become. I could possibly be the only Hongkonger who have been to Nyamata 4 times.
