So I have a 16 year old son who dropped out of college and has resorted himself to playing video games all day long. Recently, I was cleaning his room when I found out that he had left his computer on. What I've seen on his computer was some gross and obscene images of sonic the hedgehog (from those old video games), he doesn't know that I've seen them and I don't know how to talk to him about it. Any advice would be great.
