You're my life,
My world.
Forever, you'll be in my heart.
Through tough times and good times. 
I know we can make it,
Because we have before.
When you leave, you're taking a piece of my heart. 
Because I'll love you forever, my sister.

We're not really sisters,
Our parents wouldn't last.
Complete opposites,
You know the saying.
Opposites attract.

I sometimes think,
You're replacing me.
But then we have a laugh.
And realize, that will never happen.
You're mine forever, dear sister.
You'll be with me forever, dear friend.

This is all from the heart, none is a lie.
I couldn't make this up,
Even if I tried.
I've never loved a friend such as you.

You're hard to handle, dear sister.
But I'll put up with it,
If it's the last thing I do.
