Can't tell if you are serious or not, but I really never do hear white people talk about extended family like black people do. For example, I have no idea who my parents cousins are (for the most part) and this was absolutely fascinating to one of my black coworkers.
Blacks have larger numbers of children than whites do today so they have much larger families. They also have more extramarital events creating confusion, auntee becomes a term of art not a term of kinship. If your mother has babies with four different men how many more family relationships are created between step siblings and relatives of putative fathers. If your mom goes through a variety of serial extebnded relationships, how many more friend contacts does the child get?
I encounter professional white people who I view as nearly aliens on a daily basis.
What does that mean? Culturally different? They speak a different language? No shared values?
