In all the decades on this rotating rock for me it would be the worst of human nature. The greed, the backstabbing, the me, me, me attitude, the "I do not care" about another poor soul, unless of course it is coming home.
I have had and also seen so many people that are so damn ultra self-centered that they could never see past their noses, just so sad.
Always remember that one leaves with, what one came with NOTHING, and it is what a person does while here that matters so much.
