We do like to decorate a tree and a few other decorations around the house - but we don't have a Santa's grotto effect. I really feel Christmassy when the tree is up though, especially on real tree years (we put up an artificial one on years we will be away over Christmas itself - so that includes this year).
Gifts are important - but more in the giving than receiving. I like to get things that match the person - personality, needs, likes. I love to craft gifts but don't usually have enough time. But I make sure I have something for everyone on my (long!) list. And I love whatever I get in return from whoever gives me something - I don't expect something from everyone on that list.
Foods are important. We don't tend to go overboard that much - but we do like to do a proper turkey dinner. I get a pack of amaretti biscuits as a treat to me. We have some seasonal treats bought, and we make some cookies and mince pies - but we also have plenty of nice but healthy options too (so chips to go with hummus or dips, but carrots sticks too, and bowls of olives to nibble).
If I have time to do things homemade, that is great. But the way my life is and the pace it moves at, I know I won't always get that chance. And often, taking small nuggets of free time to relax and unwind instead are more important to keep me moving forwards - there are plenty of nice shop bought options which won't "spoil Christmas", and having a more wound up and stressed me is far more likely to spoil the holidays than not having HM mince pies and cookies or 3 different stuffings...
