As a teenager, I just want to point out a few things.
-if you scream at him, or raise your voice, he's going to be deffensive. If hes about to go on the computer ask him quietly and nicley to play a game with the family, uno, monoply ect.
- Don't make him go to church. Instead, keep up with family prayer and family home evening. Find his Patrichael Blessing and set it on top of the computer. Give small hints of the Gospel, but don't make him go to church.
-If he's being a bit on social, i suggest calling one of his friends up and asking him to come over and hang out with your son, cause he's feeling bad. Make sure this friend realizes your intentions.
-Pray for him.
