Hindi school or corporation school?

This was Pandey Sir of NHS(Boys), Calcutta.

Sunil Pandey was a teacher in National High School (Boys). He taught commerce cum discipline (not a formal subject though). Since this was a boys’ school, maintenance of discipline was considered to be a separate and mammoth task. I am not sure how Mr. Pandey got elevated to the position of discipline teacher. Perhaps he was the pioneer of the subject in the school as there were no other teachers of the same subject.

I remember one incident when I had my only face-to-face interaction with Pandey Sir. We had our chemistry laboratory finished earlier than the expected time. Chemistry ma’m Mrs. Sunita Chandrasekhar told us we that we can go. She actually meant that the lab was over and that we can go out of the lab and stay in library or in classroom. But few of us understood it to be a Go-Home signal. So, we left the class and started to go out, it was around 10-10:30 AM, while the school used to break at 11:10 AM on non-lab days and 11:50 AM on lab days. The guard noticed the swarm leaving the main gate and called us shouting. By then, two of my friends had went around 50 metres and I had almost crossed the gates. We were all called in and asked stay in the big hall in the ground floor and then Pandey Sir was called.

It looked as if Pandey Sir was always in lookout for an opportunity to take discipline classes like this. He asked the two fellows who had crossed the gates why did they leave the school. They responded saying they were told by Sunita Ma’m. But Sunita Ma’m clarified that she didn’t ask us to leave school. Pandey Sir again hovered on all of us. He then asked me why did I leave the school. I replied that since we were told by ma’m and my friends were going, so I also followed. He then looked at my face and asked me if they jump into a well shall I follow them? I couldn’t reply. He then asked me “Coming from a Hindi School or Corporation School? ” I again explained him the reason but surely his 'comment' died down. But this comment weighed heavily on my mind. I didn’t complete my previous schooling either from a Hindi or a corporation school, but was it a crime or a guilt to belong to either ? Corporation schools in India do not maintain disciplines properly. I didn’t mind this incident to be related with them. But, why Hindi ? Pandey Sir’s was the typical attitude of the educated class towards Hindi, the national language of India.
