the last letter

Why do you treat me as if I was only a friend
What have I done that has made you so different and cold
Sometimes I wonder if you'll be contented again
Will you be happy when you are withered and old
I cannot offer you diamonds or mansions so fine
I cannot buy you the clothes that your young body crave
But if you'll say that you long to forever be mine
Just think of the heartaches the sorrow the teardrops you'll save
While I am writing this letter I think of the past
And of the promises that you have broken so free
And to this old world I'll soon say my farewell at last
I will be gone when you read this last letter from me
