<U>Comment from student</U>: Hello, mam respectfully don't bother to answer my question if you don't understand 
or if you don't know the answer let another tutor answer.

<U>My response</U>:


When the tutor answers to the student, the student must stay in attention.


The only words he can say in response are "Yes, sir", or "Yes, maam", or "Thank you".
