Cards? A commercialised pain in the colon. The ones that really piss me off are the corporate ones - I recall interminable hours spent signing reams of cards to people I lcouldn't care two hoots about, and every time I receive one I'm underwhelmed by the gesture.
Best card I got this year was from Charlie, the local Big Issue seller in Beaconsfield. That and a couple of home-made jobs were the only ones that actually lifted me and made me think warmly of the senders.
As for the rest - a shocking waste of card, ink, saliva and postman's bunions!
Of course, as an insidious Roman Catholic consipracy, the plan to overwhelm the postal service with meaningless mail must be fought... (Bloody hell - I've just turned into a troll. Nurse! The screens!!)
