Since the Chief and I didn't travel for Christmas this year, we actually decorated (our first Christmas tree in years!) and even had a party Friday night. I hadn't expected so many people (anyone, really) to bring gifts of wine - we started the evening with 7 bottles of red wine, for example, and ended up with 12! This despite people actually drinking the wine we had on offer. We could have at least 2 more parties without having to buy a single bottle! Very little beer was drunk, either; the Chief had bought a goodly variety, very little of which was consumed.
Leftover food was easier; the cookies went to friends' house the next day (they were having a holiday brunch w/ optional cookie exchange), and we didn't have all that much left of the savory stuff - maybe 1 cup of dill dip, no more than 2 cups of hummus, and enough salmon spread and salsa for a nice Christmas Eve dinner. 😊 Some of the veggies got sauteed to accompany our Christmas lamb chops, and most of the rest went into a big pot of veggie-beef soup I made last night.
Next time we won't have to spend nearly as much on party supplies - we won't have to buy anything but food, as we have MORE than enough alcohol for at least one more party, maybe 2 or 3.
