Why is life so unfair?
It gives you things like happiness and love, and then takes them away with no promise of return. You face abandonment, betrayal, pain and an insane amount of loss.
And for what?
For a few years of a miserable life not lived?
Life promises things like fame and fortune; but when you reach the top you're still unsatisfied and when you're at the bottom, the view upstairs looks pretty great. But no matter where you are, life will always leave unfulfilled and weeping.
So why have any high hopes from life?
Because by the time you figure out what it all means, you'll be too dead to care.
