Ethnically speaking, the only one that comes to mind is fika, a Swedish/Scandinavian practice of afternoon coffee and some sort of baked good. Except when I do it, it’s often a Clif bar and a bit of cold brew.
Growing up, most traditions revolved around the holidays– Thanksgiving and Christmas. For Thanksgiving, we’d have the big meal at either our house or up at Gram and Gramp’s, and everyone would be there– aunts, uncles, cousins, it was quite a crew. We started a Christmas Eve tradition of gathering at our house– everyone would bring a dish to share, there’d be homemade sill (pickled herring) and hardtack, some gift giving, and then an 11pm candlelight service at church.
Now that our kids are married and off in a few different places, we’ve started gathering at our house for Thanksgiving, where at least two of our three kids and their families are in town for food and fellowship over the course of 2 or 3 days. And my wife and I have been making the 12-minute trip to our son and daughter-in-law and their four kids for Christmas morning. Breakfast and gifts under the tree.
