By this point in the semester you're beginning to get the lay of the land. You've navigated the administration of classes, bookstores, parking passes, and coordinated the eight different campus offices required to pay for it all. You are likely carrying several more pieces of plastic in your wallet and have dozens more passwords floating around in your head than you did a month ago. You've hopefully also gained at least a vague sense of what is expected of you as a student, as a TA, and as a colleague. Often such expectations are not written down anywhere and get relayed inconsistently if at all.
