My mind and my time have been preoccupied this week because my older daughter is graduating from high school this weekend. I’ve been to her art show, awards ceremony, spring concert, banquets, parties, the baccalaureate service, and still have more to come. We’ve assembled a dress, mortarboard, tassel, gown, stole, and honor cords to wear. It’s hard to remember, but both my graduations back in the ‘70s seemed simpler. I could have worn the same cheap black gown for both high school and college graduation. And the same gold tassel, too. So I took a look at the history of caps and gowns for an article I wrote for mental_floss.
