This is just a short little thing.
Severus was sitting at the Slytherin table eating breakfast thinking about Lily Evans, the only girl he can ever love. Yes he had not spoken with her for almost two years now, but he was making a plan on how to tell her he loves her and her seeing that he was really sorry about what he said. His thoughts were interrupted by Lucius speaking. "Potter actually got it right." Severus looked up from his plate to the direction of the others gazes around the table. The first thing he noticed was that the whole hall was staring at the doors. Then he really saw what they were looking at. James Potter and HIS Lily were together she was smiling up at him. A deep blush on her cheeks. Potter looked like he owned the world. Lilly was speaking to Potter non-stop. It almost looked like she was dancing around him. This didn't really bother him that much. He knew it was going to happen with both of them being Heads. The real thing that bothered him was how they both looked at each other with pure, deep, I will die for you love on their faces and in both of their eyes. He turned back to his breakfast holding back tears. He lost her. He lost his Lily.
*years later*
Severus was sitting at the table eating his porridge. When he looked up the spoon froze halfway to his mouth. A feeling of da ja vu came over him. Harry and the Weasel girl were entering the hall talking and laughing. The girl looked like she was dancing around Harry talking straight on without stopping. On their faces and in their eyes? Pure, deep, I will die for you love. A feeling Severus had been hiding for who knows how long made its appearance once more. The feeling of losing one you love. Severus shook his head and went back to eating, pushing the feeling deep down. "They look just like James and Lily". He heard Dumbledore whisper nearby. He got up and walked out of the hall.
