To be safe from bullying, you first need to have a good background, that means you can’t be known as the kid who nobody likes, and you also need to defend yourself or ignore them, as that is what makes them stop. You can also get people you trust to defend you, friends, family, etc. if your getting bullied the best possible way to stop it, is ether put your foot down, or tell a adult. Some adults will not help you, however, usually not giving them a reaction will get them to stop, but if the EVER put their hands on you, by all means, put them where they belong. If you get what I’m saying.
