My family never had or did anything on Thanksgiving that lasted more than a year or two and so nothing made it to the "tradition" list. We typically had turkey at church on Sunday the week of Thanksgiving, so we always got our turkey fix out of way before Thanksgiving. We did get together and spend time together eating and eating and eating. It's just that nothing repeated year after year. Very little changed even after I got married and started a family of my own.
My husband and I still don't cook a traditional turkey feast or any sort of feast, but we do have something we can humbly and shyly call a tradition. Every Thanksgiving, we wake up pretty early, put on a sweater and Uggs. Then we head over to the Starbuck across the street, grab coffee, walk couple steps across the parking lot, stand in a line mostly of men and wait paitently for our Marie Callendar's Pecan Pie(s). Yup, that is our Thanksgiving tradition. We go get coffee and pie together as a family. We have done it every year ever since we got married and so it feels very special that we have our own thing that we do. Depending on the plans and who we'll be getting together with, we make sure we get several to gift and share. I can honestly say that we don't do it because it's just easy (although it is undeniably easier compared to actually baking a pie), but because we really do enjoy doing it every year and find ourselves looking forward to it. To me, that itself is worthy of being called a tradition.
