This is a great idea. I married into a family with tons of food traditions, that — experiencing them as someone coming into it from the outside — feel like the amount of stress the celebratory meals cause for all concerned outweigh the upside. I honestly wish a magic wand could be waved where they would be willing to do this, and see what a holiday was like without the unnecessary performance anxiety, imposed expectations, and constant buzz of stress in the background of everything. Also, lasagna is awesome.
