Christus Mansionem Benedicat
See http://www.liturgy.co.nz/blog/epiphany-chalk-house-blessing-2/4942 for more details of the blessing of your house at Epiphany.
Also: UK readers who used a debit/credit card on New Year's Eve should check statements carefully that they were not double charged. A processing error suggests that you may have been. If so, talk to your bank, not to me.
As for me, it's cold and dark and I don't feel very festive yet.
