     Sometimes teens need to have some time away from their families. They may want to move out of the

family home for a while. Many parents will say no to this demand. But experts say it might be a good idea

to let your teens live with a friend or relative.

     "It was the break I need at the time," said Richant Lerner. He is talking about the time he spent living

with grandmother when he was 15.

     "It allowed me to be a different person than I was with my parents," Lerner said. He now heads the

Institute (学会)for Children, Youth and Families at Michigan State University. Experts say teens living away

from their families can test new ways of thinking and getting along with people. They may see new solutions

to problems.

     This is different from running away, the experts stress (强调). Runaways are often feeing serious

problems.

     Some teens who want some time away from family attend a structured summer program. Others live for

a while with a relative or with the family of a friend. If there is a conflict (冲突) at home, having a teen live

elsewhere can benefit other family members. It gives everyone space to develop better relationships.

     Joseph Kett teaches history at the University of Virginia in Charlottesville. He says living at home until the

late years has become the norm (准则) only in recent times. "In the 17 th century, children were often sent to

live in other people's homes when they were about 10 or 11," he said.
