Fun fact: you don't actually need to go to France to see Paris (:

PS. My layover in Frankfurt ended up being way longer than expected. First, they changed my ticket to a slightly later flight (for free). Then it turned out there was overbooking and they were looking for volunteers willing to hang around the airport for a couple more hours in exchange for a small bonus. Since things weren't going according to plan anyway, I figured what's a couple more hours. Third time's the charm—everything worked out!
