I have thought about this so many times. No one is truly who they seem and so many lives have tragedies few recognize. I will see a person driving a car or in a mall and think about how they continue their own life completely disconnected from those in my circle. Most of us will enter this life and exit with hardly a ripple and honestly what is the difference. In the larger scheme of things we are insignificant.

All the world's a stage, and all the men and women merely players: they have their exits and their entrances; and one man in his time plays many parts, his acts being seven ages.
