As I learned when taking classes on becoming a Foster Parent. Most kids don't know "It's not that great". Mom can be a druggie and Dad an alcoholic, but they are still "Mom and/or Dad" they can live in a horrible slum, in a "house of squalor" apartment, but it's still "Home".
The boy that was supposed to become my foster son decided to stay on the westside of Chicago, even though he would have far more and better opportunities, in school, in sports, and in his future life. Yet he decided that that was where he wanted to stay... C'est la Vie.
