After college, I went backpacking through Africa, and at the Khartoum airport in Sudan I met an American guy named Chris. We explored together for a few days and went our separate ways. A month or two later, I stopped by the main post office in Nairobi, and there he was again: Chris. We chatted and parted. A few months on, I was playing soccer with some boys in a village in Malawi, and who should show up but Chris.
