I think you’ve officially arrived when you begin receiving “crank mail” (i.e., incomprehensible ramblings from crazy people). Well, I just received my first piece of crank mail today.
And, of course, for it to be authentic, it has to be paper mail and include something in addition to the letter (no idea what it is; looks like a voodoo doll or a burnt piece of wire):
The letter was kindly forwarded by Tom Flynn and the good people at Free Inquiry. Please enjoy my first piece of crank mail – I know I did.
