In Karachi, Pakistan, there is a bus service that gives passengers a tour of some of the city’s landmarks. Armed guards on board promise protection so that the wealthier residents of Karachi, among others, can safely explore their own city. “Bulletproof Bus” is a story of that bus was the result of that. Usually, when I start writing a story, I step around the main idea, typing paragraphs before I begin to pin down the picture in my mind. And sometimes, in that process, the main idea morphs into something else, as the characters in my drafts react to events and make conversations and think and feel. I have learned to be okay with taking my time getting to know my characters, with feeling around for the right tone.
