I think working in mental health you have an expanded definition of suitable behavior. Just like you'd have different sets of expectations for other illness types or ages or groups, etc.

A potty training toddler may still piss all over the bathroom, or paint the room in the morning with a paw full of last night's stool. For most people that's a bit much to think about... For a parent.,, it's just another day. You clean the room and the child and keep going. If he is being ethical and can competently help you and accept and appropriately deal with your whatever actions you have/had/overcome/develop... Then I don't see it as anything pathological that he kept working with you.

I will occasionally share stories I've read here with my T. There are certainly things she wouldn't let fly as a habit but would still attempt to work with the person through.
