Summarize this article:

You are family, though that doesn’t mean you should know everything about each other’s personal lives. Be respectful of personal space, like bedrooms, journals, or cell phones.   Remembering your sibling’s boundaries will show them your love and respect. Don't read their journal or snoop around in their room when they aren't home. When you feel angry or upset, you will likely start a fight. Work on your emotions in healthy ways rather than taking them out on the people close to you.  Try venting to a friend or to your parent about what is on your mind. This will get rid of your feelings so you don't carry them with you next time you talk to your brother. If you’re really angry with your brother, rather than yelling at him, try writing a letter. This is a safe place for you to vocalize your true feelings, without maybe saying harsh things to him right away. After you've written your letter, you'll be able to discuss your feelings calmly. It’s easy to forget your sibling’s friendship if you’re stuck fighting all the time. Show your brother or sister you appreciate them by doing something nice, for no reason. It’s easy to take your family for granted. You can do things like buy them ice cream or a coffee when you are running errands. Also try things like playing their favorite game together, or buy them a new coloring book or magazine. Whether you share a room with your sibling or you live across the country from each other, it’s important to spend time together when you can. Spend time together that is positive and fun, rather than spent arguing. This will strengthen your relationship and you are less likely to fight. Do an activity you both enjoy, like playing golf, walking in the park, or watching a sci-fi movie. If you tell your brother that you will stop teasing him, do it. Be accountable to what you agree upon, and your sibling will start to trust you. Trust is important to maintain healthy relationships and prevent fights.  If you both agree your fights are starting because you want to be the boss, stop ordering around your sibling and let them make decisions. If your sister doesn't trust you because you always shoot her with your Nerf gun, try shooting a stationary target outside instead.

Summary:
Respect your sibling’s personal space and privacy. Express your emotions and feelings in healthy ways. Do something nice for your sibling to show you love and care for them. Spend meaningful time together, as often as you can. Build trust by following through with your commitments.
