They got into an altercation. Mostly verbal, with a little mutual physical contact. The caregiver shared, "I could have snapped his neck." The friend called 911 and what psych. in-patiented. It's my gut feeling that, no matter how my friend might try to manipulate his way back home, and minimize the incident, and perhaps the caretaker's words were "just an expression," but, I wonder if these two guys should go back to working together again.
