My family is pretty small. When I was growing up, it was pretty much just me, my parents, and my grandfather. We'd have turkey breast, stuffing, cranberry sauce (if my mom remembered to prepare it - she forgot half the time), and some type of veggie. My birthday is around Thanksgiving, so dessert was always an ice cream cake.
Nowadays, my husband and I live not far from my parents and in-laws, so we visit both sets of parents over the course of the long weekend. This year, we're going to my parents' for Turkey Day, and they're doing the turkey breast, stuffing, etc. that they've always made. On Saturday we'll visit my in-laws.
My mother still serves ice cream cake for dessert.

The only difference is that the cake also has my husband's name on it; his birthday is a few days after mine. *sigh*
