Oblivious

I think you are Saran Wrap: clear and clingy, sometimes helpful, sometimes invisible. People use you, but complain about you when they don't need you. You keep things from really going rotten, but you never get to eat. You aren't perfect, you get stuck on yourself, but 9 times out of 10, you do exactly what you're supposed to. You're reliable. You're fantastic.

Does Saran Wrap know it's fantastic? It should.
