Fights in the family
You feel old enough to make up your own mind, but your parents always think that they know what’s best for you.
So, how can you deal with this problem?
First, teenagers can try to look at things from their parents’ point of view. Parents often have “long-imagined futures for their kids,” US psychologist (心理学家) Nick Friedman wrote in Psychology Today. This means that when our parents control what we do, they’re only trying to guide us. Our parents have been through many more things than we have. Th
ey were once teenagers themselves. So, it makes sense to trust their wisdom and experience. After all, they don’t control us to be mean — they do it because they love us.
But let’s also look at things through a teenager’s eyes. Many teens feel like they should be given more responsibilities (责任). However, parents often do not agree with their children’s decisions. Instead of just accepting their choice or arguing with them, you should try sharing your feelings with your parents. US psychologist Carl E Pickhardt wrote in Psychology Today that sharing feelings with our parents can lead to positive (正面的) changes, while not sharing them can cause misunderstandings.
