"If someone is bullying you, just ignore them and walk away."
I always had a huge problem with this advice because:
1.) You can't leave school grounds or, in most cases, the immediate area where you are being bullied. I guess I am just supposed to walk out of class out of nowhere? Yeah, schools love that.
2.) I did try that in a setting where there weren't authority figures around. I was rewarded with a free shot to the back of my head.
3.) Despite what out of touch guidance counselors will tell you, doing NOTHING shows the bully that they can get away with walking all over you. Actions speak louder than words.
