High school, round 2

I met some of my students for the first time yesterday in the cafeteria at dinner.  Did I mention that I'm slightly afraid of high school students? especially girl ones? especially french ones??  Anyway, I was so nervous and flustered about the idea of going to the caf by myself with a bunch of french high school students that I got there after they stopped serving dinner and ended up eating one of the leftover plates that they save for students who do after-school sports.  There were 3 boys there (almost as scary as girls) and I managed to eek out my end of the conversation in mediocre french, resulting in them thinking that I had come there to learn french, not perfect mine after 8 years of study.  The situation was slightly helped by the fact that they knew I was their English assistant, so I was slightly impressive.  In fact, the students actually call me "vous" instead of "tu" which is weird, and the teachers tell me to call them "tu" instead of vous, which is weirder.  In order to avoid being rude, I have basically always called everyone "vous", especially especially teachers.  Also, I'm allowed to hang around in the teacher's lounge.  Being at high school is weeeeird.
