And there are enstranged families. A sort of common occurrence nowdays, but not unknown in the past either (concealed, suppressed, being a shame, common occurrence of the present is perhaps due to less stigma nowadays). They do not want to live or even be in contact with those who gave you (you gave to) their values, efforts, view of life. Lived together for years and years in dependency. People with very strong ties, like it or not.

Yes, this must be for people with highly common way of current thinking (current, momentarily, as people do change when they go through significant life experiences, like raising children or joining a community).
