My best best best Valentine’s Days have been the ones when I was single and spent the evening (either on my own or with a friend) with a pizza and a box of chocolates and some romantic movies. BEST. I was sitting here feeling sorry I couldn’t celebrate it that way and it occurred to me I absolutely could. I think next year I’m going to start that as a family thing: we can get pizza, I’ll get a big box of chocolates to share, and I’ll pick the movie(s).
My wine-and-appetizers group had a Galentine’s Day party, and I super recommend doing that if you have any inclination. A few years ago my aunt said that her life advice to me was to invest time and attention in friendships with women, and that’s another thing I super recommend if you have any inclination. I think there is a lot of emphasis on investing time and attention in romantic relationships, and I’m not saying DON’T do that, but I AM saying I am finding in many ways I get a greater return on investment from time spent with friends.
Anyway: the Galentine’s Day party. A perfect excuse for inviting a bunch of people you’d like to get to know better, if you’re feeling short of friends; or a lovely friendship-affirming party for people who are already friends. Doing it potluck is delightful, because you get to eat all kinds of things, and you know there’ll be enough to eat, and it greatly reduces stress on the hostess. Our group likes to do BYOB, but it would also work well to buy a few great honking bottles of wine in various colors (I recommend emphasizing pink and white varieties, and get at least one fizzy one) and set those out, along with wine glasses. (And/or soda/water with cups, if your group is not as winey as my group, or if it’s a new group and you don’t know how winey they are.)
In unnecessary-but-nice, I like to use this excuse to buy heart plates and heart napkins: at least two plates and two napkins per person. (It’s common for people to use one set for savory and then a second set for sweet.) And put out forks and some serving spoons, because almost for sure people will bring things that need forks and serving spoons. If I think of it, I like to make sure I have the following pantry items Just In Case: bag of tortilla chips, bag of potato chips, box of crackers, extra wine. Every so often someone will bring a dip or spread and have forgotten the chips/crackers, and it’s just nice to be able to casually whip out a bag/box.
Then, especially for a first-time Galentine’s Day party, or for a group that doesn’t all know each other well, I suggest a classroom-style valentine exchange: specify that you are talking about a return to the fun of classroom exchanges, and that the exchange will consist of literally things such as paper Wonder Woman valentines with a Dove Promise taped to them; those paper valentines that have lollipops speared through them; homemade cut-out construction paper hearts decorated with stickers; those Fun-Dip packs with one dipping stick + one flavor of powder; heart-shaped snack cakes; etc. Follow the example of our genius elementary-school teachers and have everyone just fill out the “from” field, not the “to” field, so that everyone can just walk along dropping an item into each waiting box/bag. I had on hand a bunch of heart-covered lunch bags bought on clearance a previous year, but you could ask people to bring an empty (DECORATED??) cereal box or whatever, too, labeled with their name.
Established friend-groups can wing it more with the gifts; setting a price range would probably be a good idea. I am trying to think of some of the things our group has done. Mugs. Pretty shot glasses. Little succulents in hand-painted pots. Bracelets. Hand-made necklaces. Cans of spiked seltzer / mini bottles of booze / those cute little bottles of wine. (Cans/bottles of fancy coffee would work well too.) Pretty little jars full of pink/white/red M&Ms. Little heart-shaped boxes of chocolates. Assorted Valentine’s Day candies with “Happy Galentine’s Day!” stickers on them. Pretty notebooks. Plus, a lot of us like to buy the same kits the elementary school kids use, so there’s a scattering of paper valentines with jelly bracelets, decorative erasers/pencils, temporary tattoos, etc.
Music! I suggest estimating the approximate years the people you’re inviting were in middle school and high school, and making a playlist of popular songs from those years.
