I had seen you before, too many times to count, but a farewell that my family threw for yours, at our house in Inman Square, is when I begin to recall your presence in my life. Your parents had decided to leave Cambridge, not for Atlanta or Arizona, as some other Bengalis had, but to move all the way back to India, abandoning the struggle that my parents and their friends had embarked upon. It was 1974. I was six years old. You were nine.
