Every teacher wants that his student be successful in his life, not for the greed of money but in the greed of name, like the student which is serving in IPS was a student of my 10th - 12th batch.
All teachers are with a good behaviour but the students made him rude because of student's behaviour. Some student tolerate them while teaching or explaining a topic.
When I was in Class 10, My english teacher Ram Raj Sir teaches us very well but due to the some student's behavior, our teacher got anger and then they left our class by saying I would never teach this class.
Like this many students tolerate the teacher after all they leave teaching which cause like the brilliant students who can do anything in life left behind in life.
