Memorial Day was a few days ago in the United States. I usually celebrate it as the unofficial first day of summer by going to see a summer blockbuster movie with friends [I saw Solo: A Star Wars Story this year.] I just came across an article about the need for social scientists to do more research on how and why holidays have moved from rituals of civic pride and remembrance toward family-oriented celebrations. This article was published in 2002, but it is still very much relevant today!
