Tourist Guilt

At the beginning of our trip here, time seemed endless, and now as we have merely a matter of days I have to be more selective about what I get to do in Rome. Here is when tourist guilt particularly sets in. What have I been doing these past six weeks? What haven't I seen yet, what are those places that everyone who visits Rome hears about and always means to see? And I am also torn by questions like what is worth seeing again and which of my favorite places should I go back to? In this last week, I will try to frame my entries to respond to these questions.
