When a student is disrespectful to me, I have to be willing to lose the battle. In other words, I must resist the urge to admonish, scold, lecture, get even, or otherwise attempt to put him in his place.
i will Stay calm and Take a deep breath to quell any angry feelings rising up inside me . Remind myself that I will be much more effective, and the situation will go much smoother, if i  maintain emotional control, In the immediate moments following the incident, I will not say a word,  Simply maintain eye contact with the student and wait. Let his words hang in the air for several seconds, leaving no doubt about what was said, how it was said, and who is responsible for saying it.
Then I will clarify to him that he acts in a rude way and breaks one of the class roles by doing that. 
After that I would tell the class the certification I had that would make me a good teacher even if I am in a young age, and how this is better for them because I can understand them in a better way. 
At the end I will start the class regularly like nothing had happened.
