I have another PSA coming up when the Holiday season actually starts, but i think I need to say this as I've seen a lot of "Can I have your address?" posts going up.
PLEASE DO NOT SEND ME A HOLIDAY CARD.
Holiday emails are fine. Holiday gifts both in physical and electronic forms are unnecessary but will be received with gratitude and love. But please do not write my name on a piece of paper and put it an folded piece of paper and have it put on a fuel-burning vehicle. The carbon footprint generated by snail mail in the UK - not even mentioning airmail - is bad enough, but Enfield Council do not provide local paper recycling for our neighbourhood, and I can't access collection centres very easily.
Please consider spending what small money a card would have cost, on something more meaningful for yourself, someone else, or the planet.
(P.S. That's not to say I don't still appreciate letters, but they contain more.)
