Terrance knew that sometimes it was simply best to stay out of it.
“It’s none of my business!”
He kept repeating this to himself as he watched the scene unfold.
He knew that nothing good would come of him getting involved.
It was far better for him to stay on the sidelines and observe.
He kept yelling this to himself inside his head as he walked over to the couple and
punched the man in the face.
