Dear colleague. I know that you’re a student at Hopkins, so you must be bright. Maybe biostatistics comes incredibly easy to you. Maybe you’re just here to get an easy A. I’m not. Most of us are not. We’re here because we want to learn some difficult concepts to apply in our careers in public health. If you’re going to surf the web and read gossip blogs, may I recommend you don’t sit at the front of the class and distract all of us behind you?
