[originaltext]The evidence for harmony may not be obvious in some families. But

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image of unhappy teenagers locked in their rooms after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. “We were surprised by just how positive today’s young people seem to be about their families,” said one member of the research team. “They’re expected to be rebellious and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel Lazall. “I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
