Wow...I agree! In the 3rd day of detox isn't a good "family time" moment.
My son wouldn't talk to me for 2 weeks in rehab. Blaming me; hating life; agitated etc.
I didn't want to talk to him either!
Then....a switch and he become "normal." Someone that could think logically and talk like an adult.
I think whatever talking you do, at this point, is fruitless. He still is getting stabilized.
