Discipline in schools is welcome. But a headmistress here may have gone a little too far when she took a pair of scissors and snipped out the hair of over 100 students. On Thursday when these students of Paraswanath English Medium School here walked into school, little did they know they would be punished for sporting long hair. But when their headmistress Manjula Dhani advanced towards them with a pair of scissors, they realised they had erred in flouting the school's advice of trimming their favourite Dhoni haircut. Noticing that even after a month's notice, the students hadn't heeded the instruction, the headmistress decided to take the the matter into her hands.
