Nothing Lasts

Nothing lasts.
Strong as a rock?
Rocks turn to sand,
Sand is washed away by the sea.
Nothing lasts.
Love stretches into eternity?
But even eternity ends.
Nothing lasts.
Circles are endless?
It had to star sometime,
What begins, ends.
Nothing lasts.
Best friends forever?
Forever isn't very long.
Nothing lasts.
You said you'd always be there,
But nothing lasts.
Where are you now?
You didn't last,
Will I?
Nothing lasts.
