Christmas can be stressful for many. What stresses do you experience/ What could be done to ease that stress?

I prefer to avoid the schmultz and ads too. I can switch it off easily enough at home.
And it's less intrusive in a rural area. Down in the village, everyone has put up lights - not so much because they are believers but to attract tourists.
In the nearest town, every shop has had it's Xmas decorations up since early November - one-quarter of the year! But then again, business has flat-lined. No one is spending on anything beyond necessities. Shop keepers are desperate to try to stay afloat. 

I remember when I lived Sydney it was inescapable. Supermarkets and shopping centres playing musak versions of carols. Shockingly extravagant decorations made of plastic and tinsel that would all end up in landfill. Santas on thrones with children on their knees for photographers - the smallest in tears, terrified of the strange big man in red. It was a season for endurance and patience.

I remember those days when my children were young. The major stressor was their mother. She thought she was the queen of x-mas.
