I think one of the hardest things to accept in others is that they have a past. The idea they existed before you, and in theory, can exist again without you. It isn’t necessarily a depressing idea, the thought we wander through life intertwining our existence with others is intense and fascinating. It reflects on ourselves, how much we impact others, will our presence be memorable?
We question others past because we ourselves want to be significant. We want to mean something to those around us. We don’t want to be a phase, we want to be a purpose.
