Dillon was acutely aware that there was someone on the other side of the sofa he sat on. For the first few seconds, he figured it was a better idea not to look—close proximity to strangers tended to make him nervous, and barring his family, everyone here was a stranger to him—but after awhile, he turned his head and glanced at the person. The girl.
He immediately wished he hadn't.
Dillon's capacity with the opposite sex was limited, to the point of being nonexistent. Even just socially, he tended to make a fool out of himself when dealing to a girl not in his family. But... he couldn't just get up and walk away. That would be worse than if he tried to gut it out.
After a few seconds, he turned and looked at her again, nodding a quiet greeting before he turned and looked back at the game. Don't speak unless spoken to, and keep your focus on the game. Then maybe you won't notice she's there. Or she'll forget you're there. A simple solution to a far from simple problem.
Except for the fact that he knew that she was there now, and ignoring things that he knew to be true had never been Dillon's strong suit.
