other than, parent issues...disrespect, late payments and the like! I have terminated one that I can think of due to child behavior...I had brothers who were very violent with each other and extremely disrespectful toward me (when I tried to hold a boy still from a massive tantrum, he began kicking me, tried to bite me and stuck his finger nails in my arms) his little brother would bite and pull hair on others for no reason and the two of them fought like that with each other as well....I have no patience for that type behavior in my home.
