Passage One
Sharon Keating was worried about her kids when she got a divorce. Her daughter, says, "I was feeling.., like down and sad and even though I didn’t really show it."
Judith Wallerstein says problems from divorce can stay for many years. They can show up when the kids are adults. As adults the kids have trouble.
Wallerstein studied 93 children over a generation. The results can only be found in her book.

A. have their marriages fail as often as others
B. stay married two times as long
