Alin didn't notice Serena beside him for a moment, too caught up in reading and his thoughts, but after a moment he glanced up and noticed her. He smiled softly, even though he wasn't much of a social person, he was glad that Serena had noticed him. She was his best friend, his only friend actually, and was one of the only people he felt comfortable around. "Sorry I didn't say anything to you earlier, I didn't know if you would of wanted to talk to me or anything...Sorry." Apologizing, he did that a lot, even though usually he hadn't done anything wrong. He looked down, avoiding her eyes, feeling bad for not talking to her earlier and thinking that he did something wrong.
