What advice would you give a friend who was being bullied?

To not be afraid to stand up to the bully and don't be afraid

"Don't ever let your guard down. Don't let people better themselves off your expressions. Be stronger than that, and realize only you know yourself best. They assume."

In all realist cases, report to an authority. Have something done. Don't let it sit around and linger out longer than it needs to. Make sure you go to someone who can keep an eye on it, not someone who will just talk to someone and hope for it to stop.
