Regarding what you should do, I don't know because I think everything is corny
My mom's side of the family is a fairly large Italian-American family, so we have Thanksgiving at my mom's parent's house. I think a typical Thanksgiving only has about 20-30 of the possible attendees between my family, my mom's 5 siblings' families, and various other family members. My generation has a very wide range of ages, not to mention both of my brothers have children now as well, so the range of ages at our Thanksgiving covers them all.
Cooking is spread out so that different people bring different things which tey have proven themselves good at. The turkey is, of course, cooked at my mom's parent's house. My mom brings her green beans almondine (with and without almonds since my brother is allergic and I don't like them) and yams (of course with brown sugar and stuff), and various other relatives bring lasagna, corn, broccoli casserole, etc. We have a healthy mixture of traditional Thanksgiving foods and Italian foods.
Dinner is typically around 3:30 or 4. My grandpa picks someone to say grace, which is always ad lib. Typically someone from my parents' generation does it, but now that me and my brothers are old enough we might get called on as well. I've only done it once so far, and probably won't again for awhile since I did a terrible job after being taken by surprise
After that, we eat
Oh yeah, and then the stereotypical loud Italian talking begins. Seriously.....Thanksgiving is VERY loud
Aside for that, we don't do anything special really. I think that just getting together and enjoying one anothers' company (as can be seen by how much any one person is likely to be teased
) is good enough. Some of my cousins are prone to make comments regarding how "crazy" or loud the family is compared to your typical family, but I like it. I think that my family's candid tradition, if you will, makes it all the more enjoyable to be with one another. So, I guess one could say it's also a Thanksgiving tradition to be loud and have friendly debates (that any outsider would think was an argument)
Either way, I think it's fun and personally I enjoy having a Thanksgiving with more of a social than procedural tradition.
