[ getting to know sam winchester has been a pleasure.
he's young, but he's smart, and more than that he is engaging, and that is something that too many full-time, serious students sorely lack. castiel doesn't consider himself particularly entertaining, blames his lack of friends on it rather than his own introverted tendencies, but the point remains that his peers can be so terribly boring that it's all but mind numbing to spend time around them. research labs are enough to make him want to suck his own brains out with a straw, sometimes, and that's saying something, considering his threshold for entertainment is really rather low. and there are some of them who aren't so bad, really, but it isn't like the movies make it seem, that's for sure.

it had started as a tutoring job. sam had asked for a little help understanding his physics course, and someone had directed him to castiel, who had graciously, if uncertainly, agreed to do it. he doesn't fancy himself a teacher, and he certainly didn't think he'd be very good at it, though after a stiff and uncomfortable start, sam had begun to warm to him, and castiel found that he was glad of it. he'd worried that the gap in age might have been a deterrent, but sam is friendly and more mature than any undergrad he's ever known, and they get along well, swimmingly even now that castiel has begun to open to him more, unfolding himself bit by bit as their friendship develops into something more comfortable, something less about classes and more about simply spending time with one another.
they study together twice a week, on fridays and tuesdays. sam doesn't need much help with physics anymore, so castiel brings his own books and notes, works on whatever it is that he's writing or researching while sam buries himself in biology or organic chemistry. it's nice.
it's friday today, when castiel arrives at the little house sam rents off campus, and he tightens his overcoat against the brisk spring breeze as he moves quickly down the block; it's not far from the campus, so castiel always walks. he's rounding the corner when he feels his
