DEATH. It's all the same thing. You do something stupid and end up croaking, but why? You work so hard to reach your goals. Achieve at life, to end up laying six feet under? What is the point of living if it all ends so fast? You hear live happily from complete strangers. I don't see the point in living like so. How could someone live happily, knowing it is all going to end...
I don't know if I achieved that to your eyes but I tried to shape the poem as a skull to symbolize death.
