Once I graduate, I want to become a CPE (main conselor ?). In Paris, it's called Conseiller Principal d'Éducation and they're working in high school with teenagers from 12 to 18 years old. 
They have a lot of different tasks to accomplish during the year and schools couldn't work without them. 
When I was in high school, I lived way too far from my school and I couldn't take the bus because they were too slow and I wasn't able to be in class in time for the lesson. So I was sleeping at school. I had my room on the first floor that I shared with two other girls. We weren't very friends but it was okay. We had to share the bathrooms with every girls from the first floor. In total we probably were 20 girls and the bathrooms were too small. They were very old and crusty. A piece of fabric that once was a curtain was the only thing that could separate the girls while they were showering. It was moldy and grey but I guess it was white years ago. The floor was broke and we could hurt ourselves on the pieces. The drain was always full of hair and it was really gross. 
Before the end of my second (en première) year of high school, I talked to my main conselor at the time. I told her how bad were the showers and that I won't take a shower in the bathrooms if they weren't repaired. At first, she wasn't listening to our needs but we talked about doing a strike and then, she magically changed her mind. 
When we came back at the beginning of my last year of high school, the bathrooms were totally different. First, they had doors ! Doors that we were able to close and lock ! It looked like paradise to young teenagers. One of the shower was destined to disabled people, it was larger with a ramp and it could fit a wheelchair. There were mirrors on the walls and we were finally able to look at ourselves before going to class. Things changed because we demanded it. Administration felt threatened by our strike so they listened to us. 
I don't want to be this kind of main conselor. It made me want to do the difference. I want to listen to teenagers' needs, help them and I want to create a safe place where they feel like someone cares for their well-being.
