It is the tradition in my Catholic family to announce every year that this year, we were going to midnight mass. Then we would have Chinese food, eat a lot, and agree that next year, totally, midnight mass. This is the primary religious rite of our people. (Catholicism in my family is really more of a cultural identity than a faith.)
My husband is Lutheran, however, and it took a few years for him to understand this tradition--one year he actually tried to find a church that had midnight services! Dear lord! Can you imagine!?--but now we have crab rangoon and agree that next year, we will actually look up who locally has midnight mass, and spend a pleasant evening at home with wine and Chinese takeout.
(My family also opens the presents on Christmas Eve so that everybody can sleep late, which he considers weird. We compromise. By which I mean that I usually hand him his gift as soon as it arrives in the mail and sleep late anyway.)
Merry Christmas to all who celebrate it, and a nice day (hopefully off) for everyone else.
Dies Natalis Solis Invicti!
