hanibal,
This is 21st century. In 20th cetury we used to stand when class teacher entered the class room and again stand when class teacher left the class after end of the period in Schools. Teacher used to adopt extreme measures on students, from canning to physical punishment due to home work not done or due to indiscipline. I am talking about private schools in Karachi,
Have you ever seen how teacher reacts in Americal Public shcools when students misbhaved or do not do their home work? How they encourge students to pass the exams when they are failing? When comparing to my time and present time in school systems in America, I am astonished how teahcers abused students for no reason or even minor indiscipline. Were teahcers behaved in Public Schools in America like teachers behaved in our country in past, they would have landed in jails.
Man come out from primitive world Ustaad, Shagrid nonsense. Perhaps this may be practiced in madrassas only. Teachers are now more like friends, mentors and helpers not abusers.
