me and my family and I are having problems with my younger brother. He's 18 years old and at the age where he won't listen to anybody he thinks he has everything under control and he has all the answers. He he goes out and parties all night steals things of value like jewelry and electronics. He drinks cough syrup in does pain killers. We've tried talking to him as a family but he treated like idiots. I am at a loss. It's funny I remember when he was still just a little runt begging me to teach him how to ride a bike.
