How about dialogs about different traditions in different families? Here �s an example (taken straight off the top of my head):
Noah: Jayla, it �s hard to believe that it �s almost Thanksgiving again. I can �t wait! My family usually visits my mother �s family, and I see my cousins again. It �s great!
Jayla: We don �t have a big family, so my mother usually invites a lot of the neighbors over. Mr. Johnson �s fried turkey is the best!
Noah: My grandmother always bakes her turkey, and then she makes gravy for the mashed potatoes. It �s delicious!
Jayla: My mother has macaroni and cheese instead of the potatoes. And she makes a fantastic pumpkin pie, too!
Noah: My grandfather hates pumpkin pie, so we usually have apple pie and pecan pie instead. After dinner, we go for a walk and then play board games. I usually beat my cousins at Scrabble.
Jayla: That sounds like fun! The men and the boys watch football on the big screen TV while the women and girls wash the dishes. It �s not fair.
Noah: Everyone helps clean up at my grandparents � house. That �s half the fun. I guess you can look forward to shopping on Friday.
Jayla: Now you �re talking!
