You may ask what exactly a dysfunctional family is, and it can be explained as simple as:
Family dysfunction can be any condition that interferes with healthy family functioning. Most families have some periods of time where functioning is impaired by stressful circumstances (death in the family, a parent's serious illness, etc.). Healthy families tend to return to normal functioning after the crisis passes. In dysfunctional families, however, problems tend to be chronic and children do not consistently get their needs met. Negative patterns of parental behavior tend to be dominant in their children's lives.
Socially this is not a topic that is not spoken about unless brought into conversation between two friends or within the family. It is honestly dreadful to hear that someone can come from such a background, or actually know that a family could just do that to a child. So many children nowadays are being raised without supervision or parental control in their lives. This then causes many out bursts from children, because they then feel free to do as they please.
