Chatting to a friend this morning and she said that of everything about Christmas, the one moment that she loves most is:
Opening the front door to her extended family when they arrive on Christmas morning –the noise and madness of way too many people crammed into the hallway trying to get their coats off while juggling presents-stuffed-under-arms and kissing the kids at the same time and handing over a bottle of wine to put in the fridge and someone calling "Can you move the car over a bit so I can pull right in?" all at once.
I thought it was just the loveliest thing – that THAT's what she looks forward to most! Not presents, not lunch, not turning on the lights of the tree, but a cramped, chaotic moment of cold air and shoe-wrestling in the hallway
