It is a given that there will be a traditional celebration. The particulars of food and drink are dictated by this tradition, though not in a rigid way as to make the menu entirely predictable. Even a passing interest in the actual event at the origin of the celebration is entirely optional, and enthusiasm and close interest in the same can even seem jarring and out of place.
