I don't really want to divert this thread too far, but this might be some interesting reading: "Domestic violence is often conceptualised as an ?adult? issue, something that happens between adults who are in, or have been, in an intimate relationship and research has tended to focus more on these relationships. In actual fact, adolescents experience similar levels of domestic violence as adults. It is also clear that domestic violence is still somewhat of a ?hidden? issue in our society; however, it is even more so for teenagers."
