I don't really know any extra stuff. About anything, or at least what comes to mind. I don't know anything extra about my job, besides what the other people already know, who have been working the same time as me.
It was the same at the bank. I didn't know the extra stuff, unless you were the new guy, then of course I knew more than you. Or the hospital, I really didn't know any extra stuff, unless you were that new girl with freckles and red hair. Then I knew a couple things. She could follow me around and I could teach her a couple things, even though I knew I was quitting shortly, and hadn't told anyone. That is why they let me be a teacher, I guess. But really besides the usual stuff, I wanted to grab that poor little girl by the shoulders and say, "If a man has a blood pressure of 78/45, that is when it is time to tell the nurse. Never forget this, even if you are babysitting and watching Moulin Rouge at 3 in the morning. Go tell the nurse." And this is the part when I would have leaned in closer to tell her, "Don't trust or like Angela. If you hit your head on a TV, she won't even care. Even if you're bleeding." And she would have looked me in the eyes and said, "I have never met an Angela that I liked, yet."

But besides that I never learned extra stuff about how girls do their hair, or what parts of the country are really nice to see, or how to poach an egg the right way. I don't even usually look up my favorite bands to see what they do in their free time, or where they were born and who they are dating. But I hope, when it's all said and done that I know a tiny bit about everything. Like, enough.
