It was December 9th when Jack decided to spend Christmas with Ianto.

It was December 10th that Ianto was made aware of the fact.

On December 13th, Jack started asking for a tree.

On the 14th, Ianto said it was too early.

On the 15th, Jack said ten days was not too early.

On the 16th, Ianto offered a plastic tree.

Jack forgave him on the 18th.

On the 20th, they cut down a tree, putting it up on the 21st and decorating it on the 22nd.

On the 25th, they kissed under it to the sound of festive music from the outside.

On the 26th, they woke up together, tangled under the sheets and ridiculously happy.
