Nora Neus writes: “On a recent spring Saturday morning in Uvalde, Texas, young library patrons were learning how to set off a volcano. With help from Michelle Ramirez, outreach coordinator for the Children’s Bereavement Center of South Texas, kids carefully poured vinegar into a glass bottle with baking soda. Almost instantly, the concoction bubbled up and overflowed, to shrieks of joy and giggles. But the activity wasn’t just for fun. It was part of a grief counseling session for children following the massacre at Robb Elementary School on May 24, 2022, that killed 19 students and two teachers.”
