Mysterious Voice

A woman was walking along a sidewalk when a mysterious voice from above boomed out "Stop!". She stopped, just as a palette of bricks crashed to the ground from a construction crane overhead. She proceeded around the bricks thankful for the warning. A few days later she was crossing the street when the same voice bellowed out "Stop!". She stopped again, just as a semi ran a red light and passed a few inches in front of her. She looked up to the sky and shouted "I appreciate the warnings, but who are you?!?"
The voice answered, "I am your guardian angel." The woman thought for a moment, and then replied "Where the hell were you when I was getting married?!?"
