Kelley was supposed to stay all the way through till the end of the summer. he ended up going back to school early to pursue the student goverment. Kelley is a real nice guy. He would stand up for anyone. It was kinda wierd when he left. Just as we all got to know more about each other, he leaves. that's the way the program works though. If he didn't leave we would have never met Paul.
I hope that kelley gets all that he wants in the future. And eventually, we will all hear that him and Christina tied the knot.
