What percent of young adults are now living with their parents? Would you believe 25 percent? It’s being named the “boomerang syndrome,” which alludes to the idea that kids go away to college and come back home to the nest to live. The survey involved people ages 18 to 34, and the latter number may not seem so young. But after graduate school or after a divorce, moving home with the parents allows these young people to regroup and save money. It can also cause a good bit of conflict. So Clark wants to stress that there should be rules. “Children” should not expect to eat their parents out of house and home, for example. Parents should also decide on some amount of rent to charge their kids. Let them live rent free for a while, but then the rent sets in. Paying for long distance calls and doing chores around the house should also be on the list. And make sure you have that conversation before he or she moves back home.
