In one sentence, describe what the following article is about:

The worst thing you can do in a conflict is reacting right away. If your sister hurt your feelings, pause before reacting. Take a few deep breaths and try doing something like counting to five. This will prevent you from blowing up at your sister, potentially making the situation worse. Use your words to handle conflict. Do not scream and yell, as you are not really communicating. Never resort to physical violence, as this will only make things worse. You also do not want to accidentally hurt your sister during an argument. Let your sister know that she has hurt or upset you. Use simple language to explain the unacceptable behavior instead of getting angry in return. For example, say something like, "Ella, do not pinch me. Pinching hurts." This is more effective than yelling or pinching back. Certain topics may simply cause arguments. Maybe your sister dislikes discussing something at school. Maybe there's an issue you simply disagree on. If certain topics tend to only lead to conflict, you may be better off avoiding them. No one sees eye-to-eye on everything all the time. If you're having trouble managing an issue with your sibling, talk to a parent. Your parents want you and your sister to get along. They will be happy to mediate if the two of you are having an issue. Do not bring it up in a negative way. You do not want your parents to think you're being argumentative or mean. Present yourself as wanting to resolve the issue rather than get your parents on your side. For example, say something like, "Dad, I'm having trouble with Sophie lately. Can you give me some advice on how to talk to her about how she read my diary?"
Think before reacting. Express yourself with words. Avoid topics that lead to conflict. Talk things out with a parent.
