The (Not so) Sleepy Way Home

Once we left Notre Dame, we got Jenn to her station so she could check in for her bus and be really early, just in case.
This is when things started to go wrong for me.
I left Jenn, feeling very empty and sick inside at the idea of not seeing her again until the school year, and I went to find the way from where I was to Gare du Lyon. That's where my train was leaving from.
Or so I thought. You know, because that's the place my train came into when I came to Paris, and there is, of course, only one station in Paris that could possibly go to Annecy. Well, I got on the metro and looked at my ticket, just before I was getting to the stop where I needed to get off in order to get to Gare du Lyon. But I needed, in fact, to go to Aucherlitz! I grabbed my metro map (that, thank god, Jenn had gifted to me for the journey so I would not have to get my own the next weekend), and frantically searched for Aucherlitz- I had no idea where it was or how to get there. I found it, quickly, and was ever-so-thankful that it is only a couple of stops away from Gare du Lyon and that I could continue on the line I was on in order to get there. The adrelanline had me breathing like a track star, I was so nervous. What if I was late? It was only 9:50 and my train didn't leave until 11, but I was still scared; I'd already mis-interpretted one thing on the ticket, what if I missed another thing?
One thing that really, really bothers me here is the use of the 24 hour clock. There are only twelve numbers on a watch- WHY do you have to include 24? People here know what you mean when you say "7:30pm" so I just don't understand the point of using army time at all.
Aaanyway, I got to the station, half an hour before the time left and made it on fine and everything. I settled in, read a bit of Harry Potter, and eventually fell asleep with my head phones in.
There were several times in the night when I woke up, realizing we had stopped or just because I had been in one position for too long. Those chairs are not comfortable for sleeping; not for that long. Eventually, I managed to fall into deep sleep.
I slept.
And slept.
And when I woke up... I looked around. We had stopped again, and there were very few people left on the train. I asked the lady behind me what time it was.
"8:30."
Hmm...
I got into my backpack and got out my ticket, and realized that I was supposed to have gotten off at 6:52.
Here's the thing: I'm really bad at traveling. I kind-of just assume that things are going to happen and they never actually happen. What I assumed this time was that the train would go from Paris to Annecy and just stop. I figured that was the point of a night train: you take it, get from point A to point B, and then you're good, you're done.
What I had not considered was that there was no possible way that all these people in this night train could possibly be going to lil' old Annecy: there are always other stops. Why I had not considered these things, I do not know. Maybe I was just tired from a weekend in Paris.
The point is: I woke up and I was not where I was supposed to be. We were an hour away from Annecy by train, and this station did not look like it got a lot of traffic. I had no idea how this was going to work.
Luckily (Luckily!!) the next train to come through on its' way to Annecy was in an hour. How am I this lucky, seriously? I went in and explained the situation to the woman behind the counter. And you know what? She didn't even make me buy a ticket; she just wrote a note on the ticket I already had and told me I was good. So I got back about three hours after I thought I was going to, rushed to my house, took a nap, and got ready for my afternoon class. It was quite an adventure in Paris.
