that they have a good relationship with their teenagers. But last summer,
Joanna and Henry noticed a change in their older son: suddenly he seemed to be
talking far more to his friends than to his parents. “The door to his room is
always shut.” Joanna noted.
Tina and Mark noticed
similar changes in their 14-year-old daughter. “she used to cuddle up(拥抱)
with me on the sofa and talk.” said Mark. “Now we joke that she does this only
when she wants something. Sometimes she wants to be treated like a little girl
and sometimes like a young lady. The problem is figuring out which time is
which.”
Before age 11,
Children like to tell their parents what’is on their minds. “In fact, parents
are first on the list.” said Michael Riera, author of Uncommon Sense for
Parents with Teenagers. “This completely changes during the teen years.”
Riera explained. “They talk to their friends first, and then maybe their
teachers and their parents last.”
Parents who know
what’s going on in their teenagers’ lives are in the best position to help
them. To break down the wall of silence, parents should create chances to
understand what their children want to say, and try to find ways to talk and
write to them. And they must give their children a mental break, for children
also need freedom, though young. Another thing parents should remember is that
to be a friend, not a manager, with children is a better way to know them.
