How do you defend yourself from a bully at school?

You don't have to take some crap from these people. Maybe you should tell a teacher about it and just talk to them about it. In my school we have peer mediation so people can find out what they can do to make things better. Ask a teacher if they could get the person who is bothering you and talk together to figure things out. I hope things work out better.

If you let bullies bother you on your brand new school year or a special event then they just ruin all you fun, so just ignore them, don't say any sayings like: "Thank you, or you made my day" you think that will bore them but it will just make them enjoy it more. so just follow my advice and you might have a wonderful year or less than a bad year.
