Different races different faces.
Our church members are mostly White people but there are two large families, one Indonesian and the other Philippines. They are very nice to everyone, except they hate each other. Newcomers don’t know they are different from each other and if they make the mistake of saying something nice about one family to another, then they get told off sharply and find themselves on that family’s bad list.
It’s funny in a way, but you can’t be friends with both families. Not if they find out anyway.
