What! So early?
Yep, but it's not what you think. All that feast of meals and unwrapping presents close by a Christmas-tree and outside the window everything is coated in thick white snow.
Nope.
How about your character is SO not looking forward for Christmas. Not only because everything's early in shops but perhaps something else is bothering ...
May it be comedic, dramatic, romantic, epic just Christmas needs to be mentioned or symbolized and the character is not happy about it.
Time is ticking, so go for it! ;-)
