“Come outside. You need to see what your son did.” Ivy’s trembling voice sent me rushing outside without shoes. Three houses down, I found my eleven-year-old son, Joel, covered in scrapes and blood, holding a screaming toddler in pink pajamas. A delivery truck stood crooked in the road, its driver sitting on the curb in shock. I demanded to know what had happened.

Three weeks earlier, Joel had begun asking permission to walk home from school alone. His father had left years ago, and I’d raised him by myself, picking him up every afternoon since kindergarten. I knew I was holding on too tightly, but the thought of letting him walk alone terrified me.
