Almost 10 years ago, I used to have materials delivered from the Builders of the Adytum to my door in Little Portugal. They were bulky letters with a rather striking sender address.

Torontonians obliged themselves by opening these letters, multiple times, out of a communal mailbox, to see what they were all about. This is an indictable offence in Canada, but neither common decency nor the rule of law actually exist in this country so that's ok.

... Unless, of course, you are Portugese - then the law is fully on your side, as a Canadian white.
