Preservatives

I'm gonna stay fresh for a long time.
No decomposing.
No food for insects,
No fuzzy white snow top of neglect.
My shelf life is expired
But I don't belong on a shelf.
(I don't belong)
I'm big enough to admit
When I've had enough of the things I want.
I need. Give me.
Preservatives.
Preservatives.
