The pen, the old wise men say, is mightier than the sword. In Kashmir, the humble pen drive has emerged as the mightiest. In the midst of a months-long communication blockade and curfew-like restrictions since Article 370 was revoked in August, education has been the hardest hit. In the gloom of the freezing season and lurking security fears, parents are reluctant to send their children to school. Though the government announced reopening of schools in late-August, classrooms mostly remain empty three months later. Thousands of security personnel deployed in the Valley still occupy many schools and colleges in which they have been given temporary quarters.
