"You were both pregnant at the same time," she says, more a statement than a question. Both women nod and after a moment's pause, Kristina adds, "What about Angela?" Kristina is referring to her 16-year-old sister. "Well..." her mom clears her throat. "It worked so well the first time, and we didn't want you to be an only child, so we did it again a couple of years later." "Swapping partners, again?" Lauren asks. "Yes," mom says. "What about now, when the four of you go to the cabin?" Lauren asks and I bet mom wishes she had never promised that she would always tell us the truth no matter what we ask. "Not that it is any of your business," mom starts meekly. "But sometimes a marriage needs something to keep it from getting stale," mom looks at Mrs. Andrews instead of us as she speaks.
