You just never know

I have recently found out that one of my closest childhood friends, a former federal agent, has been indited and, ultimately, has plead guilty to a series of very serious crimes. And I am in shock. I have not been in contact with this person much since I was in Jr. High, but not one memory I have of him could have predicted this outcome for his life. He was a very normal, very sweet kid, and I just don't know how this could possibly have happened. I am deeply saddened by this. People are so unpredictable, and I guess you truly just never know.
