Nowadays, some people may argue that parents should encourage their kids to be well-mannered, while some think it is the teacher's role to emphasis these values to them. On one hand, parents have personal bonding with their children along with love and affection. On the other hand, teachers are trained and unbiased towards their students, hence, they usually keep them in check. In my opinion, teachers job is more oriented towards the betterment of the kids and their actions, therefore, I believe that they will do a comparatively better task than the parents.
