How would you react if your friend did this?

Here's the back story. My friend Everett had long hair like mine in the beginning of the year like emo/mop like mine. Then he cut it to a buzz. So a few weeks ago we got our yearbooks and i looked at Everett's picture to see his long hair which i loved (yes i'm a guy) and my friend Emmalyn crosses out all the pictures in the yearbook of him. There's only one picture of him left in the yearbook and he crossed out some of the pictures too. And the one that's left has a pen mark down it because Emmalyn tried to cross it out but i yanked it away.
