One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

Listen—Listen when they are talking. Don’t say anything unless they ask you a question. Sometimes it’s not necessary for you to have anything to say; they just need someone to talk to about their feelings.

Help them—If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don’t do everything they want you to do. Try to take an extra pencil or pen with you to classes in case they forget one. Have a little extra money in your pocket in case they forget something they need.

Be there for them—Be there for your friends to help make them feel better in hard times. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control, but if you can’t stay with me at my worst, you are sure not to deserve to be with me at my best.” Always remember this! If you don’t want to stay with your friends when they’re in hard times, then you don’t deserve to be with them when they’re having a good time!

_________—Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you’ll remember these things when you’re all old!
