My work

Am a great teacher that is love by all
A smart teacher
A fabulous one indeed.
One day I want to work and one of my pupil that like to think that she is all and all in my class came late to class and I ask her a question.(what is the meaning of ""bonjour""
But she was unable to answer
Still now I don't know what to do with her!!
My family,what should I do?
