The finally is the social problem, it is the social has violence as usual. Unfortunately for many, home can be anything but a safe haven. Men and women alike may find their home a fierce battleground. For children it may be where they are most vulnerable to assault, misuse or deprivation, ironically at the very hands of those who have a duty to safeguard and nourish them.

Humans are very social beings: all of our essential needs are dependent in some way on relationships, especially with those who nurture us from birth. The human brain develops in such a way that our stress-response systems are intimately connected to systems that interpret the moods and actions of those around us. When social cues tell us others are calm and safe to be around, our own physiological state is regulated accordingly and we relax our vigilance. On the other hand, when we sense threats or negative emotions, we respond by going on alert.
