13yo son totally disengaged from the world. Not super-bright but not stupid, just can't be bothered to use his brain. Does absolute bare minimum school work. When he's not allowed on the X-box and not down the park kicking a ball around has absolutely no idea what to do with himself. We've tried loads of things without any real success. Has very little general knowledge as he never reads anything. Has no real hobbies. We've tried taking the horse to water but this one won't drink a drop. He's not unpleasant - he's a nice kid, but how do you get them to grow up a bit and engage with the world? Any advice very welcome.
