Talking to a child...

So, I have a student who is quite naughty. He is the class clown.
He is always talking. He hardly ever uses his chair. He has to be reminded myriad times to do his work.

Well.. I wrote a letter to his parents to ask them to talk to the kid...
The letter says:

Dear Parents,
I am writing to inform you of Mohamed's behaviour in class. He is constantly disrupting the class. He talks at inappropriate times. He is always playing with something. He runs around the class room.
His behaviour makes it difficult for himself and other students to benefit from being in class.
Please speak to him about these issues and the importance of proper behaviour in class.
Thank you,
Nora


and...
This is the reply that I got.....


Miss Nora,
Thank you very much for your time and effort with Mohamed. I spoke with him and he promised me that he will behave himself in class. Please inform me if there are anymore problems with him and his behaviour.

Thank you,
Maha


And this is how the message was delivered.....
