My wife and I have a lovely1 tradition: our Jar of Precious Memories. During the year, every time we do something nice together we keep the ticket, receipt, place card etc., and put it in the jar. Then, on New Year’s Eve we’ll crack it open and think back. Sometimes it’s a postcard picked up during a weekend trip, sometimes it’s a movie ticket, and sometimes it’s just a receipt from our fave restaurant where we had a particularily great lunch.
That “well done, you” jingle in the NYT crossword app (you know the one) never fails to make me smile.
