I'm going to comment the new of this ip:http://www.bbc.co.uk/news/world-europe-15302674
Summerize: A math teacher sets herself on fire, students and parents said that last days she was very aggressive and hostil with some of them. Last Wednesday parents and the teacher did a meeting and it seems that she was very nervous and hostil.
I think this teacher need psycology aid, it cannot be possible that a secondary school teacher set fire to himself because she was very fragile or angry. She needs to contol herself, at least education controlers must have controlled that, a discontrolled teacher is a bad person to educate childs.
French education must control his teachers, make a psycology test or something like that.
To sum up I would like to say that this is not a fail of the teacher it's a fail of French education system.
