My ex-best friend Stole herself from me

Before I said I knew you
Like my frount door
But now I see a scar
That wasn't there before

You are not the girl
That I thought I knew
You replaced that girl
New attitude,clothes and shoes

I think you are a devil
That rose up from hell
Who stole away my best friend
And broke me as I fell

Believe me when I say
No one wants to know you
You've gotten so low
Treat people like gum on your shoe

Sadness fills my eyes
And I'm sure it's here to stay
For this evil little being
That took my best friend away
