No, I didn't. I see a large number of homeless and mentally ill people in my job. By the way, although they overlap some, not all the homeless are mentally ill and not all the mentally ill I see are homeless. Firstly, if I pursued the story of all who interest me I would have no time to get my work done. Also, I have to maintain a professional demeanor. I would not ask other customers about their personal lives, so I don't see why asking these people would be appropriate.
I know there are two schools of thought about forced medication, and I can see both sides of the issue. However, when I see a very intelligent person, not the bus stop lady, another person I deal with, who is unable to function, and who might be helped by medication, it does make me sad.
