My whole focus was on the small girl crying on the sidelines. Shannon. She was holding her school jumper in her hands and sobbing inconsolably, while her big brother comforted her. I felt something then, a lurching sensation in my chest, as I took in the sight of her torn jumper. Anger. That’s what I was feeling, and it was bubbling inside of my stomach, growing hotter with every tear that spilled from her eyes.
