The less you say, the better. You don't have to explain yourself. > I wish I had a polite answer to "where are you headed tonight?" "I prefer not to answer" or "I'd rather not say" are both quite polite. If the questions persist, you can always say you'd prefer to answer questions in the presence of your attorney, which you should do anyway.
