WASHINGTON -- There was a time when Tope Folarin came almost daily to the Politics and Prose bookstore in Washington not to sip iced lattes, as he's doing on this recent Sunday afternoon, but to learn his craft by reckoning with language. Back then, he sat in this bookstore cafe and copied poetry into a raggedy notebook."It pained me that I couldn't afford to buy the books," Ogden-born Folarin says, leaning in to take another sip.Four years ago, as he wrote down verse after verse, his academic pedigree as a graduate of Morehouse College and a Rhodes Scholar were meaningless. He was out of work and unsure where he fit into the Washington scene. He did know that the story he would someday tell would be of the complexity of blending cultural and national identities. In his case, Nigerian and American.
