We all know what the word Christmas means – it's the celebration of the birth of Jesus. Christmas Day is 25th December, the twelve days of Christmas run from then until Epiphany, Christmas cake and Christmas pudding are both delicious breakfast foods, a Christmas card is a pretty picture sent to prove both you're not dead yet and that you don't hate the recipient.
A Christmas rose isn't a rose at all – it's a hellebore. They don't usually flower on Christmas Day, but do bloom soon after and are very pretty.
The true meaning of Christmas is far less clear. Mostly it seems to be a festival dedicated to spending money, overeating and getting stressed. Or maybe I'm just cynical and it has a more positive meaning for you?
Whatever your feelings about Christmas, if you can express them in a story you could enter the first of Wordsmag's 2019 short story competitions. These are free to enter and offer cash prizes. (I won the Christmas one last year.) If the festive season really annoys you, maybe you'll prefer the theme of the second competition?
