I once had a conversation at school with a first grade student. It was snack time, and, as she saw me approaching the eating area, the student called out to me:

“Mrs. McDavid, Mrs. McDavid!” Olivia’s hand was up and signaling for me to join her.

I walked over to her table and sat down. “What’s up?”

“Did you know that before, if we were at a school with all black people or a school with all white people, I couldn’t sit with you?”
