Michael practically vibrated with energy, pacing his small apartment. A rhythmic tap-tap-tapping of his foot against the hardwood floor filled the room. The air buzzed with a potent anticipation. He’d known this day was coming, but he still couldn't believe it. He picked up his phone, dialing his friend, Leo. The phone rang, then, *click*, Leo answered.

"Leo, you won't believe this!" he practically shouted into the phone. "They actually published it!" There was an excited gurgle in his voice. He had to be calm.

He heard the words leave his mouth. He could barely contain himself. He took a seat on the edge of the couch, bouncing his leg in anticipation. He didn’t notice the absence of the writer’s name. He just kept talking, telling Leo about the article.

He was surprised at the lack of reaction. "Wait, did you say that was under… someone else's name?" Leo's voice was filled with a certain tone that Michael had never heard before. Michael paused, looking at the page, which he had printed.

"Oh."
