So have you ever started talking to someone at a pivotal point in either their or your life when you have to say to yourself "ok you probably wont see this person ever again"?
It sucks because those people are always seem to be so sweet. Its always like wow we could have been really good friends, but now nothing.
On another note, I've discovered my love for Facebook, not that I ever disliked it but yeah. For someone like me who has moved around so much, you can find like any friends from any point in your past. (granted they also have to have a facebook, but most people do)
