"What are you doing in there, waxing your mustache?" Iggy yelled, pounding on the bathroom door. I yanked the door open and pushed him backward hard, making him stagger. "I don't have a mustache, you idiot!" Iggy giggled and put his arms up to protect himself in case I punched him. "And you know what?" I added. "You don't have one either. Well, maybe in a couple years. You can always hope." I left him in the hallway, anxiously fingering his upper lip."
