Sam looked down at her, hands instantly sliding into the front pockets of his jeans, shoulders squaring up a little at an uncomfortable angle. It was something that he often did when he was around women that made him nervous. It was an odd realization, that one. Faith was making him nervous.
"Hi," he shot back, returning her shy smile with one of his own. He seriously felt like a teenager, stooping up to some girl's house during their first date. He was supposed to be better at this, wasn't he? No, Sam wasn't Dean. He didn't have all the charm and the witty lines. But he was a grown man! No more high school, little boy behavior!
...oh, if only it were that easy.
"Uh." He shifted his shoulders up a little, brows rising with the gesture. "How are you? Can I come in, maybe?" High. School. Boy. He looked down nervously and laughed. "I swear, I'll stop acting like a nervous kid in a minute." There! Admitting that he was nervous. That was an adult thing to do. Also something that most men would frown upon in this sort of situation. But this was Faith. He could push the tough guy act aside and try the more...honest route. Maybe.
