What is the best present you have received this year? We'd like to hear from the grumpy, too.' Photograph: Malcolm Piers/Getty Images Guardian writers can be a miserable bunch. December had barely begun before George Monbiot was bah-humbugging about the planet-destroying nature of many of the "gifts" we give our loved ones: There's nothing they need, nothing they don't own already, nothing they even want. So you buy them a solar-powered waving queen; a belly-button brush; a silver-plated ice cream tub-holder; a "hilarious" inflatable Zimmer frame; a confection of plastic and electronics called Terry the Swearing Turtle; or - and somehow I find this significant - a Scratch Off World Map. They seem amusing on the first day of Christmas, daft on the second, embarrassing on the third. By the twelfth they're in landfill. A few days later, five more of our resident miserablists remembered the worst Christmas present they had ever received - for Jon Henley it was a scratchy vest knitted by his granny, for Paula Cocozza a model of the Millennium Dome hastily made from an upturned cereal bowl and 12 matchsticks. Not to be outdone, Charlie Brooker looked around at the hordes of austerity-defying pre-Christmas shoppers, each with "the face of someone quietly praying for a stun gun to the temple or some Dignitas vouchers for Christmas" and asked: What are these people buying, what does it say about us as a species, and which of these gifts has the potential to destroy humankind? Now the big day has come, the presents are unwrapped, and we want to hear from you, our cheerful readers. We'd like to hear from the grumpy, too: feel free to hide behind anonymity and tell us about the worst gift you unwrapped today. And, if you want to come over all Guardian about it, what do the presents you received say about us as a species - and do any of them have the potential to destroy humankind?
