You're an open person most of the time. You have nothing to hide, so why should you waste time covering things up? This may be true, but today you should guard your privacy at all costs. Certain people are trying to find out what you're up to, and their motivation could be jealousy. They could also just be looking for fodder for gossip -- and they could easily twist the situation to make you look less than stellar. Tell anyone who asks you what you are doing to mind their own business. They don't need to know.
