If your boy doesn't want to engage, it's better for life. Too many people can become cloying, trying to please them all. He will make friends as he goes through Life. Does he have hobbies. Do you do stuff as a family? My neighbour took one of her children out on Sat., she often picks one of them to have a day with. The rest stay back doing other things. Gives her 'ear' time with them ;-)
