My favorite is St. Nicholas Day on December 6. My Oma and Opa (grandmother and grandfather), who lived next door to us, would have a roasted duck or goose dinner which ended with a spice cake dessert. Then Opa would go get the advent wreath, which laid flat on the round table in the parlor (so you could light the candles). Oma would play the piano, and we all sang "Stille Nacht" (Silent Night) in it's original German. (I was 7 before I realized the words I sang to Silent Night were different from my classmates.) Then Opa would light the tree while we sang. After it was over, he would give my father a half bushel basket filled with oranges, apples, small wrapped dark chocolates and small wrapped presents for my five siblings, me and my parents. It was the kickoff of our holiday season.
My second favorite tradition was English crackers at the breakfast table on Christmas morning. My Opa was 1/2 German and 1/2 English. His father spoke mostly German and his mother spoke mostly English. My mother would make two Apple Puff Pancakes, sausages, strong black coffee, and apple juice for breakfast every Christmas morning. Then we would sit down to breakfast, open our crackers, have several good laughs, good food and good family.
My parents only gave us three presents (because that's how many Baby Jesus got for his birthday.) We would open them after breakfast -- I'm pretty sure that the strong black coffee for breakfast was my father's idea since we wanted to get up and open presents at the crack of dawn!
I forgot to add that the six Hummel angels that Oma and Opa had on their Christmas tree (one for each grandchild) now have a home with love on my Christmas tree.
