As much as I've wanted to do it, I've never done this to my kids. When my best friend was 10, her mother was dealing with alcoholism. Drinking and driving in those days was a common occurance. BF had another friend spending the night with her. They left their home in Hollywood and went to Bushwood to visit her mothers friend. On the way home, at nearly midnight, the mother did this to the two 10 year old girls, pulled over and put them out and drove away. The girls walked until they came to the first house and rang the door bell. Finally someone opened the door to the girls. They explained what happened and the other girl called her parents who drove from Hollywood to Bushwood to retreive the girls. Very true but sad story. The only good that came from this is the mother realized she had hit bottom and put down the bottle for good. We are now in our 40's, and the mother has remained sober.
Lets hope this mother too will receive the help she needs, whatever that may be.
