Problems

I´ve had a problem recently. My brother Ruben doesn´t go out very often and he is all the time playing video games. I´m worried becouse its important to go out with friends. I know that my brother have a lot of friends. I think he should go out more often but maybe he is so young and its only problem.
I´d really like some advice becouse if i don´t do something soon, we´ll probably have a argument
