I follow Marcia Brady on Twitter: Mo McCormick, Actor/Author. She posts a video with her older brother and they dance, a fast waltz, under an oak tree with dozens of hanging pastel paper parasols. She holds his hands, looks up into his face: he watches her feet. I wish we were friends. I’d call her, Mo, too, one syllable, low: prayerful, bovine. Mo asks her brother, do you have a girlfriend yet? She leads, spins him around: I love her in a way I couldn’t back then.
