At 9.30 pm every night for 30 days now, when most people are safe at home and relaxing after dinner and roads wear a semi-deserted look, 46-year-old Rizwana Siddiqui is preparing to brave the freezing cold of this Delhi winter and spend the whole night at Shaheen Bagh, where a group of courageous and principled women have led a remarkable sit-in protest against the controversial citizenship law. Participating in the protest demands more from Rizwana than the fortitude to brave winter nights - before she leaves home she must ensure dinner is ready. She is also an asthma patient and must take her medication and use a nebuliser before heading out. She must also remember to pack an inhaler in the sweater she wears to the protest site. None of this would be possible without the support of her family, she says.
