My best friend?

My best friend
How could you do such a thing?
My ex-best friend
This is what you have become.

My best friend
How did I lay trust in you?
My ex-best friend
What you did was so low

My best friend
I used to tell you everything
My ex-best friend
I can’t believe you did

My best friend
The one I used to cry on
My ex-best friend
Now I don’t even want to know you

My best friend
Good-bye forever and ever
My ex-best friend
I never want to speak to you again
