I met the school class teacher of my son yesterday

And she seemed as complete nuts ,not half but completely non sensible.While that made me chuckle about her expectations from students in terms of discipline and professionalism,

now I am really worried about the future of my son and his friends.
If a few teachers who are responsible for the welfare of the students and society at large are lunatics ,what world are we leaving the next generation ?

Disappointing.
