If John didn't want to see Sam again after the boy had decided to go study at Stanford, then it was his loss. Because all Sam wanted after all that had happened, was to have a normal life; without the paranormal. Without kitsune, without ghouls, without vampires. Just for once... he wanted to choose.
And maybe Sam was being petty as he ignored Dean's calls, texts and everything else. But did he felt guilty about it? Not really, because in the end, he was finally able to live his life exactly the way he wanted to.
And Stanford was so much more than what Sam thought -- it was big, it was filled with friendly faces, classes he had to try his best to understand, it was filled with thoughts of you.
If anyone asked Sam about you, he'd probably start stuttering and talk nonsense, his cheeks taking a rosy color. Because yeah, obviously he had a crush on you; who didn't? You were always so nice to those around; taking notes for your sick friends, keeping a seat for the late ones in auditoriums, letting people use your stuff.
And what Sam liked the most about you was probably how you always waited for him at the end of the literature class -- when everyone walked away but you stayed just for him. You both walked through the campus, talking about the day and what your group of friends said at lunch.
That day, Sam thought he should take the courage to ask you out -- because he wanted a normal life, and a normal life would mean having a partner, right?
"Say, I-- I thought it would be nice if we grabbed coffee or something? Let's say, tomorrow, maybe?" he asked you, walking by your side. There was the smallest of smile on his face. "You can say no, but... it's a date. I'm asking you on a date, I mean."
