A good teacher is the one who wants her/his students prosperous and shows the right way when they are heading towards a wrong way. S/he might be sometimes harsh in her/his words and tones when showing the right way but s/he has always the best interest in them. Parents are also the first teachers to their child. So, the teacher and the parent are regarded as someone who gives us invaluable treasure. One can be prosperous with the guidance of a good teacher. We should be the one who cherishes and re-pay the enormous gratitude of our teachers and parents. We should not be the one who acts against them. 

Sadhu! Sadhu!
