Firts impression..

I was wondering always how important is that first impression. In life I figure it is not so much, however in classroom seams it can be more significant than somewhere else. In class if teacher comes and does not menge class it can be disastrous year a head. Imagine losing respect of students on the first day of teaching...it may bring year of misery.....Teaching is hard, it takes time effort,good will and practice  to hsvr respect of students may do great job in handling class...
