Don't insult him for having too much time as a kid when you're an adult. I'm 15 and I have a good idea on how he manages his time. He probably gets home from school, works on homework for a few hours, then eats dinner. What is he supposed to do then? He can't hang out with friends because it's a school night and there isn't enough time, and it's too dark to go outside. That's why he plays video games. Also, like I said, you're an adult and should have more going on than he does.
