Most teenagers feel sad or afraid when their parents fight. They might think their parents don’t love each other any more.

In fact, it is normal for parents to disagree and argue sometimes. They might disagree about important thing like jobs and family decisions. They might even disagree about little thing that don’t seem important at all – like what’s for dinner. Maybe sometimes parents feel so strongly about their differences that it may lead to arguments. However, these arguments are often over quickly. Parents may say sorry and make up , and the family returns to normal

As a family member, you should find out what it really means when your parents fight. When your parents get angry with each other, they might say things they don’t really mean. If your parents are fighting, don’t worry too much about it. Try to find a good way to solve it.

If your parent’s fighting really bothers you, you might find it hard to sleep or got to school. If this happens, try talking to your parents. They may not even realize it until you tell them how their fighting has influenced you. You can also tell other relatives, a teacher or a close friend.

Just remember that no family is perfect and arguments are common in every family.
