All he does when he gets home from school and during the weekend is play his computer games

my parents don’t seem to have a problem with it because its easier for them to leave things the way they are instead of enforcing rules.

Even though I’m studying a few hours each day for uni, acting as a role model doesn’t help

I want to help him, but i don’t want to ‘parent’ him either

please any suggestions would be grand ^_^
