In my first year of highschool, I made one of my lifelong, closest friends, by helping him out with someone who was constantly harassing him in the cafeteria. He wasn't saying anything back but I knew the words were hurting- enough was enough. I wasn't mean, but I did take the guy's tray, and moved it to another table basically telling him to get lost.
The thing is, I'm from a native reservation where I was bullied in public school because of my weight (I was a chubby kid ok? haha) so I knew what it was like, and I don't wish that sort of mental/physical anguish on anyone, ever. I had the opportunity to speak up and I did, and I will continue to do so every chance I get.
