Envy

The livid days of yesterday

Show through today

He watches the wall

Not saying a thing

He lives around

Never leaving your side

I can't always see him

He's dark and never ending

Shows up nowhere

But is everywhere

He is your worst nightmare

And your best friend

Growing up with him 

We die by his side 

Have you guessed him yet

It's a trick on the eyes

My shadow is feared

By none except me
