Like a family, we've all had similar experiences. We all know what it feels like to go into our mother's or sister's closets, and try on their clothes. We can be out and free to each other, in a way we can never be in the straight world. In all these ways we're very much a family.
Some families are healthy families.
According to psychology, a healthy family is one not threatened by differences between family members. It embraces them, and allows them to flourish. This is the idea that life will only tolerate so many different needs. In such a family, everyone is expected to look and act the same. Anyone who is different is viewed as a threat to the family and is punished.
