Nothing. I am too curious and would never return mail. One time I got a post office notification to come and pick up a registered letter that I needed to sign for. I was worried that it might be some sort of trouble. It was just a notice that a utility was gonna be clearing brush on my property sometime this summer. Crap!
Yet another one of those silly, frivolous subpoenas you keep insisting on sending you me. I have told you a million times that I'm not afraid of you or your lawyers. ~
