Opening a pair of new pajamas on Christmas Eve
Opening presents one at a time so everyone can see what everyone else got (this quickly disintegrates every year into everyone simply opening presents willy-nilly.)
Chinese for Christmas Day dinner (This one has nothing to do with A Christmas Story, it's just a delightful, and rather delicious, coincidence.)
Watching Greg in the New Year's Eve show at Hale
Life Savers Books in the stockings
New Year's breakfast of Belgian Waffles and omelets
Christmas breakfast casserole
The cousins gift exchange
Jumping on Mom and Dad's bed on Christmas morning - though in recent years they've been getting up earlier than us due to their extreme old age ;)
In other news, at one of the holiday get-togethers this year (which were rather plentiful) I had an old moment. I was watching all of the little kids playing and remembered being that age at the family parties, and it felt weird to be a grown-up at the Christmas parties. Life marches on.
