Paranoid and distrustful

So I just got a phone call about someone making a surprise delivery to me and wanting to confirm my location. I did so. Now I'm burning with curiosity (y'all know I almost always read the last couple of pages in a book when I'm about 1/3rd of the way in right??). BUT I'm also a little wary. My first thought, could this be a process server? (I know there's NO logic.. I don't even know what I could be served for, but you never know...) I hope it is not and it is actually something good. I'll keep you posted.
