The unforgettable Curse

I am a very nostalgic person and find comfort in the past.
In 2015, sitting in the back benches of my tuition class(studying math & stuff) I and the guys were disturbing the class. We were always very ignorant of whatever was taught in the class and used to make fun of the teachers. Little did I know that one of my teachers will tell me the biggest set of traumatic words that will change the course of my life. Annoyed by our constant hooting and 'chakkallas' our physics teacher turned towards us with a grim and heavy face. We knew we had done enough to get a 'lecture' of sorts 'again'. But this time it was different, he opened his lips and said the worst possible thing I ever heard. He said-

'Bahut mja aarha hai tu log ko, abhi dost log acche lag rhe hai, karle jyda din nahi hai 12th k bad dekhna kon kha jyga, ek dusre ko yad bhi nahi rakhoge'

I knew then something was strange about this. But soon after 12th ended we were struck with this reality. Most of my friends got separated, many left studies due to family pressure and started doing menial jobs, many switched to different disciplines. The girl I loved then, moved on to a wonderful college only to disappoint me with 'Who Raman?'
Despite all this, I never thought my childhood friend would be separated from me. We were studying together for past 5 or so years. Regardless of all pressure from our parents we never left each other's side. The memories of our first cigarette  to our first girlfriends we had seen everything together. But 12th changed it all, it's been years we hardly meet.
Everyday while going to bed the words of that physics teacher rings in my ears. It was not a warning, it was a curse.
