No matter what kind of bullying comes your way, do not let it hurt you, most likely the person bullying you is the one with issues. You can choose not to respond, but if you feel the need to, be sure you don't bully back.
If you are going to respond to a bully don't do it in anger or retaliate by being nasty back. Just state your case clearly and move on. Most people just like to ignore it and move on with their lives, which I usually find works!
