Heart-to-Heart Talks with Parents

As is shown in the bar chart, children spend less time having heart-to-heart talks with their parents when they grow older. For example, while the 7-9 age group spends as many as 6 hours per week on average, the 16-18 age group spends only half the time.

There are two major reasons for this: both parents and children are too busy working or studying, and there aren’t many topics of common interest for them to talk about.

In my opinion, children should let their parents know more about what they are interested in. At the same time, parents should spend more time talking with their children and sharing opinions with them. Only in this way can they better understand each other
