You have reason to feel paranoid, but every reason to learn not to. Have faith in you that most people aren't going to do that. You have to learn to trust people (Holy crap! I said that?!?!).
But if you're the Jim, you might find your Pam. If you're the Dwight, you'll only get your beets and the suit your grandfather was buried in. Somehow I feel both silly and positive today. Hmm... Sillitive or posilly?
