A seven-year-old boy asked me to walk him home. Something about his request caught my attention. I had no idea what I was about to discover.

After spending several years patrolling around an elementary school in West Portland, I had come to think I understood every sort of problem a child could possibly bring my way.

Lost lunch boxes. Disagreements on the playground. Missing tablets.

Skinned knees that seemed catastrophic until a teacher appeared with a cartoon-covered bandage.
