The taste of hot coco
The taste of cookies fresh from the oven (if they're gingerbread even better)
Sound of my cat purr-ing
Feel of my cars soft fur (the two combined are a tonic for all that ails)
Smell of a open wood fire on a cold evening
Collection of boxes under the tree, gifts for family+friends

Sooooo...

Sitting down with a cup of hot coco and a fresh Gingerbread cookie, in front of warm fire, with purring kitty in my lap within sight of the Christmas tree and presents all aglow in the lights... Heaven on Earth.
