Read the passage from the essay "War Stories: A Bosnian-American Retraces Her Father’s Footsteps.”I could tell my father wanted to give me answers but something stopped him from being able to delve directly into the truth. It seemed like the only way he could think about the war was in short bursts that flashed by quickly enough to repress any emotions they might stir.I watched the facade slowly chip away around him so that I could finally see through the stoic, self-made man—who had juggled multiple warehouse jobs to keep up with the American Dream, moving up in position despite barely having a high school education—to the traumatised refugee beneath.It was then that I knew I had to go back to Sarajevo to try to put the pieces together myself. I would have to trace my father’s footsteps through the city with whatever clues I could gather about his life.Why does the author decide to go to Europe?
