You are here, and you're entirely unexcited by the prospect. It's been a long trip, and here you are in Paris. Expensive, crowded, tourist-filled, over-hyped Paris. You've never been a real fan...
You see the Eiffel Tower, you see the Louvre, and you're already ready to leave. But it took you so damn long to get here, that you have to stay at least a single night. You spend that night at an over-priced Youth Hostel, and spend most of the next day just wandering around, which, you decide, is really how you ought to have spend your previous day. Your day ends, as many do, at the train station.
