A determined Peace Corps worker who had not seen his sister in three years decided to make it up to her in the best way possible – by surprising her in a college exam. Kamaka Dias was devastated to have missed both his sister Kanoe's high school graduation and first day of college while serving overseas in Madagascar with the Peace Corps. The 26-year-old initially planned to surprise his younger sister after two years, but after his stay was extended, another year went by before he and Kanoe, 19, could reunite. Kamaka contacted his sister's best friend, Megan Tasaki, and with the help of Kanoe's professor at California's Azusa Pacific University, Patricia Brown, they began plotting the surprise. The Peace Corps worker told his family he would not be coming home until November, so no-one would suspect a thing. Then, having settled on a date, October 15, Kamaka and Professor Brown worked out a way a recording of a poem Kamaka had written for his sister on her first day of college could play in the exam room. But to the 19-year-old's shock, her brother appeared behind her as the video on screen prompted her to turn around. Failing to believe her eyes, she sat head in hands as her brother walked down the room to greet her, before they embraced.
