Mom hollered, “Just cut it out”!
Grandparents are too traditional and outmoded, have no reciprocal value to society due to the old age, and frankly the grandkids grow up and out to care.
The in-laws for brothers and sisters are interchangeable with brothers and daughters. Correct? Weird.
Nieces and nephews are cousins. And they got their own groups. Most don’t really get along, too.
Technically, immediate families are in. Outsiders are out. Hmm.
