I wish you a merry Christmas today.
And if you're a a Harry Potter fan:
Wizards Wireless is honoring the occasion by playing "A Cauldron Full of Hot Strong Love" by Celestina Warbeck all day.
Your presents will appear magically at the foot of your bed (I hope you don't receive any from Kreacher, Lavender Brown or the Dursleys.)
Mrs. Weasley knitted you a lovely sweater and baked you a dozen homemade pies.
Hagrid made you a big box of treacle fudge, which you should warm up in front of the fire before eating.
Don't eat chocolate cakes left in the Entrance Hall as they may be filled with a sleeping draft.
Dinner will be served in the Great Hall, and you don't have to sit next to Professor Trelawney unless you want to.
Make sure to pull a wizard cracker during dinner.
Remember that the mistletoe is probably full of knargles.
Don't forget to visit your relatives at St. Mungo's.
Be sure to leave a wreath of Christmas roses on your parents' graves.
You should feel free to pelt Percy with mashed potatoes if he shows up at your house uninvited.
Have a lovely day (and you earn ten points for Gryffindor if you recognized what Harry Potter book the title of this post comes from.)
