The issues with this are entirely different than if he were a little kid. This is an adult you are talking about and not someone parents are responsible for raising anymore. Does he live with you? It may be time to get him to get his own home. Does he have a drug problem? Keeping urine for drug tests perhaps? Treat lightly if you were snooping. But you can let his dad know. Does he keep the urine or get rid of it, I guess I should ask. Is he being lazy so he doesn't have to go to the bathroom to go?
