Firstly, I don't see any purpose in farewell while we still remain connected with the ones we like, interact & have fun. My point, don't say good bye, or else you will never meet them again. I'm still connected with people from my 12th ( it's been 6 yrs), my mates have lost connection with their friends in last 6 months. And we have the same fun as we did in our college fine. Only thing missing are those classes and college campus. For me, nothing has changed.... On the other hand, pandemics should not frustrate people, since you are always connected & don't find purpose in such events.
