3. Christmas Eve. There was a time (back when I was tiny and we still had contact with the relatives) that we would go to my Aunt's place for Christmas Eve. We'd hang out, then the kids (seven of them, all older than me) would go to bed, and at midnight they'd get woken up to open their stockings. But as the kids got older it got less fun, so the new tradition became the Christmas Eve Movie.
When we started this, only one theatre in town was open on Christmas Eve, early shows only, 3 screens. So we were pretty limited as to what we could see. Now, of course, everywhere is open, so we can be much pickier. I've already started scoping out the movies to see what I think we might all enjoy.
Sadly, the movie is usually followed by the traditional Last Minute Wrapping of Presents, because there's never quite enough time beforehand.
