The best way to deal with a bully is to avoid them as much as possible. If they don’t have an opportunity to tease you, you won’t have to deal with their insults. Develop a route that keeps you away from known bullies, such as sitting at a different lunch table or choosing a different seat in homeroom.  If you have to sit next to a bully in class due to assigned seating, ask the teacher if you can switch seats. Explain that this person is keeping you from paying attention. If the bullies are in your group of friends, then it may be time to find a different group to hang out with, especially if you friends don't stand up for you. When someone teases you about being flat-chested, do your best to ignore them. Bullies are looking for a reaction, and if you give them one they are likely to continue making fun of you. Stay cool, calm, and collected. Simply ignore the insult or walk away. This also includes interactions online and social media. If you want to, you can even delete their comments or block their usernames. If you’ve tried to ignore the teasing and it hasn’t stopped, you should stand up for yourself. Tell the bully, “Stop saying that to me, it’s mean!” or “Don’t talk to me anymore.” Walk away after you’ve said your piece and be proud of yourself for being brave enough to speak your mind. Sometimes, bullies will stop picking on you if you stand up for yourself. Try to remain calm and collected when confronting the bullies. If you appear too upset, they may continue teasing you just to get another, similar reaction. Don’t stoop to a bully’s level and trade insults with them. Instead, show your maturity by refusing to taunt them back. You could even say something like, “I’m sorry you feel that way, but I know that looks aren’t everything. I have lots of other skills and talents that make me happy with who I am.” If the bullying still continues, tell a teacher, principal, or guidance counselor right away. They may be able to interfere and stop the bullying.

Summary:
Avoid bullies when possible. Ignore taunts and teasing. Stand up for yourself. Be the bigger person.
