Summarize this article:

Having a friend with you is a strong deterrent for people who tease and bully others. It's a lot harder to deal with two people than one person. If you're worried about being teased on the way home from school or in-between classes, plan it out so that you'll be with a friend at these times. Say to your friend, "Hey, will you walk with me to class so [teaser's name] won't mess with me?" If the teasing is bad, enlist help from a teacher or principal at your school. It's their job to protect you. You don't need to feel like you're "telling" on the teaser; he/she is the one at fault and all you're doing is taking care of yourself -- and others, most likely, since he probably teases multiple people. There are things that teachers and principals can do to stop the teasing and make you feel safe. Don't be afraid to involve them. You can tell her/him , "This guy/gal is teasing me and I need help. Can I talk to you about it?" If your teacher isn't doing anything about the teasing, or if it's out of her control, talk to your parents. They can talk to someone higher up in the school's administration and get the situation fixed. It may not seem "cool" to ask your parents for help, but it will be worth it in the long run. Harsh teasing can disrupt your academic achievement and your self-esteem.  Try telling your parents, "This guy at school is teasing me. Is there anything you can do to stop it from happening? Can you talk to the school?" Some school counselors are actually trained in dealing with teasing and bullying. Going to a school counselor is a great option if you're having a hard time handling the effects of being bullied. They can help you cope with the teasing, and what you say to them is confidential. The meeting will be private and the person or people who tease you will never know. Tell your teacher that you want to see the school counselor. S/he can help you find the right person to talk to. If you need someone to talk to or want additional support, try a help-line or support group for teasing/bullying. Talking to people who are going through similar difficulties can help you feel understood. You can also discuss strategies together for dealing with being teased.
