I love Life and I love Death
For Life giveth pleasure and pain
For Death taketh away pain and gain
But I will always love Life more than Death
So let Death be my wife and Life my secret mistress
As I always know Life cometh but must be whisked away
While Death shall remain by my side from birth to my death
And although Life and Death will never meet
I still feel secretly guilty for dancing in between
But I am the light that never dies
And I am the darkness that forever stays
If not by the side of Life and Death
Who else can I be, can you make a guess?
