It's still the start of school, you've all still have nine months to go. That seems like forever, just wait until your 20s kid. Nine months...seems like nine days, what you wouldn't give to be back in the class room. Still there are nine months left to start being somebody's hero.
If you notice a kid being bullied, don't shy away from them, be a friend. Ask them to play or about their favourite music. Let them know that even though somebody or a lot of somebodies are being jerks, You'll always be their friend. Stuff like that, it means so much to a kid that feels friendless.
Teachers can't be everywhere and they certainly can't see everything. Sure it's fun to get away with things, like chewing bubble gum in class, sneaking a bit of your snack from your lunch. But bullying isn't one of those fun things a teacher can miss. If you see a student being bullied, find a teacher and tell them. A teacher can't help, when they don't know whats happening. If you don't want to be seen by other students, catch the teacher during recess or just after school.
Maybe you know bullying is happening, but you've never really seen a student doing it in order to tell a teacher. Don't worry thats O.K because there are still things you can do to help. Make a poster about why bullying isn't nice, and how being nice = being cool. Ask your school's principal if it can be put on the school's bulletin board, who knows maybe the principal will turn your small idea into a school wide project.
If your a parent concerned about bullying, be a hero, be active. Get together with other parents from the school in perhaps a PTA setting and brainstorm on school activities that would force your children to get to know other children through fun activities. Activities that would enforce the values of being kind and not being a bully. This helps in so many ways. Also be mindful of how you act at home, if junior always hears you gossiping and complaining and saying mean stuff about people in your life, they may thing it's ok to do the same thing to their school peers, especially when your kids don't have the contextual knowledge behind some of these actions that you do.
Remember to be a Hallway Hero.
