Disrespect!!!!!!!!!!!!?

MY 15 YEAR OLD STEPSON KEEPS RUNNING HIS MOUTH OFF AT ME. I'M NOT SURE WHAT TO DO, WHEN HE WAS YOUNGER HE SPENT SOME TIME IN A CHINS GROUP FOR PROBLEM KIDS, MY WIFE DOESN'T KNOW HOW TO HANDLE HIM AND HE JUST WALKS ALL OVER HER. HE DOESN'T DO DRUGS OR ANYTHING, HE JUST THINKS HE'S CLEVER AND FLAPS THE GUMS , WHEN HE SHOULDN'T, YAKNOW CL CLOWN, BUT HE CAN'T EVEN P MATH, AND I HAVE TO BABYSIT HIM EVERY DAY, SOMETIMES I GET SO ANGRY, PLUS THE STUPID UNFAIR TO PARENTS PROGRAM DSS WOULDN'T APPROVE. WHAT CAN I DO TO HIM WHERE HE WOULD KNOW I MEAN BUSINESS, AND WILL NOT TOLERATE .................DISRESPECT!!!!!!!!!!!!!…
