In a part of Uttar Pradesh where schools are notoriously deficient in attendance, visuals of a teacher's farewell with heartbroken students clinging to him and weeping, have gone viral. Shivendra Singh was transferred recently after four years at the Raigarh Primary School in Chandauli, a hilly region. Videos of his farewell on Tuesday show scores of boys and girls hugging him and sobbing. Some students hold him tight, refusing to let him go. Mr Singh, smiling, tries to reassure them, but he too appears to be in tears.
