Well, I had a little girl and I really thought that she loved me.                
So I said one day, "Darling, would you like to marry me?"
She said, "Why I would is plainly something I can't see.
"Just go away.  Get out of here.  Don't bother me!"

And I said, "Yes, ma'am, I could be gone if you want me to.
No, ma'am, won't come back when you ask me to."
And I said, "Don't you know? Someday you'll be feeling blue,
"But I'll be gone, and I won't come back, even if you beg me to.
