A few years ago, writer Rhodri Marsden was visiting his parents for Christmas.
He tells BuzzFeed: "I was just lying in this single bed with an unpleasant duvet in a rather austere room in my parents' house and thought, 'I bet I'm not the only one.'"
"So I took a picture and tweeted it. And then these pictures started coming back at me."
"For some reason they seem to collectively convey the spirit of Christmas without having any Christmassy stuff in them whatsoever."
"Just bad duvets, unpleasant curtains, and deflating airbeds."
And thus one of the greatest annual traditions on British internet was born.
This is pretty much one of the Christmasiest things you'll see.
And which is Marsden's favourite picture?
Well, that would be this one.
