WAKING up early one scorched day in Pondicherry recently, 18-year-old Nalini Vaidyalingam, wife of a watchman, took off her sari and hanged herself from the ceiling. The police said she was suffering from chronic ulceritis. A few hours later, Kumurappan, 42, and his wife began quarrelling over some trifle a few miles away. Minutes later, the farm worker walked out of his home in the neighbourhood, and hanged himself in an orchard. And as evening fell on this quiet town, 19-year-old Chitra Shankar, wife of a construction worker, ground yellow oleander seeds into a fibrous paste, spiked it with sugar, and swallowed it. At night, she lay dead in a government hospital. The police said she took her life after a tiff with her husband over his drinking habit.
