A Simple Blade of Grass

Of the billions of people in this world, together we're vied as a mass. Individually different, yet seen as a simple blade of grass. If I grow tall, shout out, or scream I will not be heard, I will not be seen. When I'm next to you, I am the same... or at least it would seem. And when I die no one will see, as another blade of grass soon replaces me.
