Suprava is a woman in her 60s. She is a highly respected social activist who, as a young girl, had taken part in the struggle for India's independence. Her only son Anjan, who has settled in the US, regularly pesters her to come and stay with him and his family, but Suprava declines, arguing that she has too much work with her organisation.
