Où j'en suis dans mon devoir

On Thursday, December 5th, Australian's people came in Léonard de Vinci. With Charlotte, Roxane, Caroline and Florian, we must do the visit of our high school to Gabrielle and Stephanie.

School visit
At first, we showed them the science labs, the ressource centre, the staff room, the education assistants, the smoking area (in Australian's school, it's forbidden to smoke), the library, the cafeteria, the lecture hall, the canteen, the applied arts department and the audiovisual department.

The applied arts department are very intersting for Gabrielle because she likes to draw. A studient of audiovisual showed them all rooms and materials : it was intersting for them... and for us too ! In the canteen, I said “Today, we eat a choucroute ! Do you know ?” and, of course, they didn't know !

Australian's high school
The private school of Gabrielle and Stephanie calls “Lavalla Catholic College” : there is two degrees : High School (around 700 pupils) and Genius School (around 1,200 pupils).
Australian's pupils work between 9:00 AM and 3:30 PM ! However, they wear an uniform, but different each seasons. They are approximately 20 studients by class, and only 8 in french lesson.
Their high school is very different of our high school : Stephanie said they have a lot of little building and each is for differents subjects, so she feels that our school is bigger because we've got one big building ! Moreover, they have differents rules : they can eat and drink during class and they can left the lesson before the end. I think it's very strange...
In their school, they have “houses”. Each house have a different color like Stephanie has an orange house and Gabrielle has yellow house.

Australian's girls
Stephanie Scarlett is 18 years old, she has one brother who's got 20 years old. She lives far enough from Melbourne, in the State of Victoria, where she goes to school, about 60 kilometers and approximately 45 minutes. She plays piano too !

Gabrielle is 17 years old, she has two sisters and one brother. She lives in Melbourne too and, of course, she studies in the same high school than Stephanie. She likes metal music and she loves to draw..

Australian's stereotypes about France and French people
We asked at them what are their stereotypes about France and French people. Stephanie talks about bérêts, baguettes, Eiffel Tower, curly mustache for men.. and they thinked we are short ! But she realizes that we are tall as them..
