I know his family. They're good people. I believe his home life is good. I'm not sure about his social life though. He doesn't seem to have many friends. He's a nice kid which is why I encourage him to make friends with my son. He is two years older than my son, but they both like playing games. I don't want to be ugly to him, but it's very annoying. I assume his family probably has different boundaries in their home and it seems normal to walk into peoples' homes and bedrooms without knocking. He seems to be bored all of the time,as he's always saying he has nothing to do. When my kids say that I give them chores.
Treat him like one of your own and give him chores! That will stop him dead in his tracks.
