A man was walking down the sidewalk. From out of nowhere a voice spoke to him. “Stop. Don’t take another step. A brick is about to fall on your head and kill you.”
The man stopped, and a brick crashed to the sidewalk in front of him. He was amazed. He looked up. He looked around. He couldn’t find the source of the voice. He kept walking.
The voice came again. “Stop. Don’t cross the street. A car is about to run a red light, and it will kill you.”
The man stopped at the curb, and a speeding car charged through the intersection. The man was astounded. He looked around, but he saw nothing.
He spoke, “Where are you? Who are you?”
The voice spoke to him, “You can’t see me. I’m your guardian angel. I make sure nothing bad happens to you.”
The man was amazed. “Really? A guardian angel? Where were you when I got married?”
