30+ years ago, I worked at a residential home for teenagers who were removed from their homes, either due to abuse or their parents'/schools' inability to control them. I worked there almost one year and was the assistant director. When we received our 100th client during my time at the home, I did some statistical research. Maybe it was an anomaly; but out of 100 clients, 99 were from "broken families."
I'm glad that you and your siblings turned out ok.
