Let me tell you a funny story that I heard about the train station in Rome:
Once upon a time, there were two travelers in the Roma Termini who were on their way back from a long day in Pompeii, and they were changing from the cross-country trains to the metro. They had passed through that same station earlier that day, and one of the travelers noticed that the path they took through the station seemed unnecessarily long. However, he also noticed that there was another path they could take through the station, which seemed as though it would reduce their walking distance by hundreds of meters. When this first traveler suggested that they take a different route through the station, the second traveler said she didn't want to take the risk that an alternate path might take them too far out of their way. The first traveler said that he was 99% sure that his suggested route was shorter, but he couldn't guarantee his suggestion with 100% certainty, so the second traveler wouldn't yield.
Unbeknownst to the first traveler, the second traveler had an ulterior motive for her unwavering skepticism: they had been traveling all day in the hot sun, and she needed to use the little traveler's room, so she didn't want to waste a bunch of time wandering through a train station if the first traveler was mistaken. However, the second traveler didn't say that she needed to use the little traveler's room, so the second traveler seemed to the first traveler like she was being overly difficult for no discernible reason, while the first traveler probably seemed to the second traveler like he was being an insensitive schmuck.
With a not-so-subtle tone of exasperation, the second traveler told the first traveler something like, "You can do whatever you want, but I'm going to follow the route that we used earlier." The first traveler took the second traveler's statement as a challenge, so he left to pursue his shorter path through the station - which worked out exactly as he had expected - and because he was also more than a little exasperated with the second traveler, he boarded the metro without the second traveler.
The first traveler pouted all the way back to his hotel, where he arrived around a half hour before the second traveler. However, the reason why the second traveler arrived later wasn't because she needed to use the little traveler's room; she boarded a different metro car because she had the first traveler's metro pass, and she spent that half hour unsuccessfully searching the metro station in a desperate attempt to find the first traveler, which delayed her departure. However, unbeknownst to the second traveler, the first traveler had put aside his sulking long enough to buy a one-way ticket on the metro to get back to their hotel.
The moral of this little tale? Don't be so secretive when you need something, and don't act like an insensitive schmuck when your traveling companion doesn't agree with you.
Nothing in that story has anything to do with my wife's and my recent journey to Rome, of course. We always made it safely back to our hotel. Perhaps we arrived together. Perhaps we didn't. Perhaps one of us arrived a half-hour after the other, but that doesn't mean anything, does it?
