Resonated with me, I've had my bullying experiences brushed aside as 'must-be minor'.
It's funny how the article doesn't embrace the obvious about why abused kids tend to be bullied and bullied kids tend to abused: that when you become a victim that you easily slip into that role everywhere; you don't know that you deserve any different.
