@PragyaPriyadarshin11, that's true, but it's always been that way. One shouldn't forget all the good things that happened, nor should one fall into despair. Some people leave, others come. In fact, it's wonderful that we can experience so many different emotions through other people. New acquaintances will eventually become old ones, and the cycle will repeat itself, bringing each of us a new and unique experience. It's a kind of circle of samsara, huh? :)
