What is a one-sentence summary of the following article?
Examine your own treatment of your classmates. Is there anyone you may be bullying, even unintentionally? If you ever pick on someone, even if you wouldn't consider it bullying, you should stop. Try to be nice to everyone, even if they're not your friend.  Be careful teasing someone unless you're good enough friends with them to know that they won't take it personally. You should also avoid spreading rumors or gossiping about people. Avoid talking about people online or sharing pictures of them without their permission. If you see someone getting bullied in your school, stand up to the bullies. Not participating isn't going far enough. Make sure that you are actively taking a stand to prevent the victim from getting harmed further. You can interfere by speaking with the bully if you feel safe doing so, or telling a school administrator what you saw.  If your friends start gossiping about someone, make it clear that you don't participate in that kind of thing. Try saying something like, “I don’t like gossip. Can we talk about something else?” If you're part of a group that's intentionally leaving someone else out, tell the group you want to include everyone, because it's the right thing to do. Try saying something like, “I think we should be nicer to Catherine. It must be hard to be the new girl in school.” If you see someone getting picked on and fear for that person's safety, tell a teacher or school administrator right away. Try saying something like, “I am worried about David. I have noticed that some of the older boys harass him when he is walking home from school.” Many schools have anti-bullying campaigns led by students who want to keep their schools safe and friendly. Join a group or start one at your school to spread awareness about the problem of bullying and figure out ways to solve it.   Try starting a conversation with your friends about bullying. You might say something like, “Did you know that bullying is still happening at our school? I think it is terrible and I would like to do something to stop it.” Talk with your teacher or school counselor about ways you can help. For example, you might be invited to give a presentation on bullying in your class or you might be able to help organize an event to raise awareness about bullying.
Make sure you aren't participating in bullying behavior at school. Stand up for people if they're being bullied. Spread the word that bullying has to stop.
