B. The problem with this is that parents give their sons and daughters no cultural values. So what happens in the TV programme? Some problematic British teenagers go and live with parents in different parts of the world. They live with families that believe in traditional discipline and cultural values.

They think they can do what they like and they are only interested in new fashions and Hollywood celebrities.

D. Why are British teenagers like this? Wiseman says it's because their parents give their children everything they can. But they give their children no limits, no rules, no discipline because they want their children to be 'free'. They don't tell their children to work hard because they don't want their kids to have any stress. E. A recent BBC television series explores these questions. It's called The world's strictest parents'. Is that because British parents are very strict? Just the opposite, it seems.
