He was walking down the dimly-light corridor that lead to his common room, one of the few places in Hogwarts School of Witchcraft and Wizardry that he actually felt at home, and safe. He really needed to get away from all the noise of the Great Hall, to a place where he could just think. Think about what they had said to him.
A bunch of 1st year Ravenclaws had asked if he was the troll that was accidentally let in on Halloween a few years ago. To be the mockery of even the first years was a real self-esteem killer. But they didn't know what it was like to have parents who thought that you could do nothing more with your life than become a henchman, to know that you are the only person going through this, to be all alone.
They don't know what it's like to be Gregory Goyle.
Gregory had a secret, one that he dared not speak about or show anyone. Everyone saw him as the thuggish bully, no one could ever see him as anything more. He told no one for fear of the consequences. For fear of the ridicule he would receive from others. For fear of what his parents would do if they knew. For fear of what the Dark Lord would do to him.
But then, he thought of Flitwick. Sweet, beautiful devilishly hansome Flitwick, who inspired him to new limits. He WOULD tell the world his secrets, for Flitwick's sake.
"Everyone, I have something to tell you. I, Gregory Goyle, have gynecomastia. I, have man-boobs. And I AM NOT ASHAMED!"
