Upsy-daisy

I don't know why, but recently the question has resurfaced as to whether it is treason to stick a postage stamp on an envelope upside down - well, it's not.  I think the idea probably originated because way back the basic common law definition of treason was simply disloyalty to the Crown, and if they'd had postage stamps back then probably affixing one upside down might well have been seen as an expression of disloyalty.  Today treason is a statutory offence and there's no mention of postage stamps, and unlike some other countries we do not have an offence of lèse majesté which essentially means offending the dignity of the Monarch.  In America the tradition has arisen of using the positioning of the stamp as a means of sending a message - as I understand it, upside down means "I love you".
