A touching commercial that rubs the deepest part of your heart

2011 commercial by MOE (Ministry of Education) Singapore.
Teachers are mentors and role models to their pupils. They influence young minds and inculcate sound social and moral values through word and deed, within and outside the classroom. They must impart to pupils learning skills, thinking skills and life skills to cope with the future; an attitude of continuous learning and improvement; and a sense of commitment and belonging to Singapore.
