Guardian Angel

Walking down the street one day, a woman heard a voice yell, 'stop! If you take one more step, you will be killed. The woman stopped and seconds later a brick fell and landed in her path.
A minute later or two, she was ready to cross the street when the same voice bellowed 'halt! Don’t cross the street now'. An out-of-control beer truck soon screeched around the corner and didn't even slowdown as it ran the red light. Shaken, the woman asked out loud, "who are you?"
'I am your guardian angel' replied the voice. 'And I imagine you have some questions for me"
'You bet I do', the woman said. 'Where were you on my wedding day?'
