Starting to end of life,our whole life belongs to teacher who teach us that thing which we never know before.Firstly ,Our parents are teacher which are teach us basics like how to speak,walk,behave in society.Later when we grow and go to school and college We see that teacher teach those students who knew that thing before but those students who learn first time they got difficulty because teacher focus only those student who knew that thing before.
So, I mean to say that teacher's are who which teach new things to those student who never know before,to stablish their all student in this fast society.
