It’s fine to be disrespectful and flippant about Angles but let me tell you my story.
Years ago I was out , late at night, in one of the seedier parts of town, walking toward the railway station. Ahead of, but unknown to me was an armed confrontation between police and a disturbed gunman.
As I approached he heard, or possibly sensed, my presence and turned his loaded gun toward me. Fortunately I was still walking in the adjoining street and since he, like everyone else, could not see around corners, my life was saved.
I now consider that intersection my Guardian Angle.
