Humans celebrate pain. We love cherishing our pain, sorrow and grievance in our subconscious state of mind. Even a love story turns out to be great when it is about unrequited love. Why one loves to be in pain? I believe sorrow, as an emotion, needs to be shared while happiness can be cherished all alone. Sharing our sorrows, pain with someone makes us feel wanted. Bad times and bad situation makes the bonding between two people stronger. Sharing happiness doesn’t create the same effect.
