My 17 yr old is like this. If I were you I wouldn't push it too hard. Children get way too much socialization in school as it is and they are constantly bombarded by stimuli and noise and some introverted kids like mine want to be left alone to decompress at home. She does have ONE friend she goes out with now but that is only since junior year and even sometimes she doesn't want her best friend driving her home even cause she needs time alone with family where it is much more low key. Maybe some of that could apply to your son? It may have nothing to do with it, but just another perspective
