In between teaching Bethesda about seven-digit subtractions and Mayan art this afternoon, I pulled on a frock and applied mascara and lip gloss. We then had a lot of fun taking pictures. (Bethesda loves photography, and has been practising making stop-motion films and documentaries.) This is one of the resulting shots, and – somewhat aptly – I’ve decided to run it as my author shot in Mama: Love, Motherhood and Revolution. The credit? All hers.
