I think for many people Christmas decorating and gifting is a lot of work - and often, much of it falls on the women. My spouse and I are childless; when we were working we often celebrated Xmas but sometimes did not. We both worked which is how we managed a very comfy retirement in a very expensive area.
But if I caught a winter cold or an emergency work project that had to be completed ASAP, then yes, Xmas decor was skipped. I love to cook, as my family does potlucks, so if I didn't have time for cooking AND decorating, then cooking took precedence.
My family gave up gifting years ago. Only two kids in the next generation, so once they reached 8 and 10 yrs old, they preferred money as they would save to buy the "extras" they wanted.
These days I'd rather gift people when I see something they would like, and give it to them next time we're together. Why wait?
Now that we're retired, I still only do Xmas decorating periodically. It's a lot of work, although we love the way it looks.
Artificial tree and garlands/flowers only. I'm actually allergic to handling evergreens, LOL. For this year I bought three new sets of the battery-operated wax candles with the realistic "flickering flame." I have some older ones, but the newer ones have a REMOTE CONTROL. I LOVE it - instead of turning 15 candles on and off by hand, we can just 'zap' it on or off!
Because they're all the same brand, one remote works for all three sets. Give me progress any day!
