I'm always the admirer of those with festive spirit regarding decorating and just celebrating holiday season basically staring 1st December.
It was sort of never a tradition inside my household, so I'm not very fond myself of such things, but I'm always smiling seeing decorated houses, lighting displays on porches etc.
As for my Christmas prep...it's kind of complicated this year. For the first time ever, mom will be abroad (work) while me and my younger sister will be together. And I'm already in my feelings just typing this. Come 24th, I will be a crying mess. We already ordered part of food I certainly won't be able to prepare by myself (my sister is not much of a cook or baker help and I simply refuse to get overdone by myself regarding preparations...), but there will be few dishes and sweet things I plan to make by myself.
I guess we will buy a small tree, some lights, festive tablecloth and...we will try to feel happy, despite mom not being with us in flesh.
Christmas or holidays are all about being with those 2 people for me, not much about festivities and whole package. And about calm, unhurried spending of this time (which is a nice and welcomed change comparing to how Christmases looked like before 2013 for me, being rather a fake pageantry of happy family cosplay, ending with tears getting into the borscht

). As this year mom is not around, everything sort of hits me harder. Plus the older I get, the more emotional I am becoming over holidays.
